1. Introduction

As the network has grown, along with it there has been an increase in the number of software tools and applications to navigate the network and make use of the many, varied resources which are part of the network. Within the past two and a half years we have seen a widespread adoption of tools such as the archie servers, the Wide Area Information Servers (WAIS), the Internet gopher, and the Worldwide Web (WWW). In addition to the acceptance of these tools there are also diverse efforts to enhance and customise these tools to meet the needs of particular network communities.

There are many organisations and associations that are focusing on the proliferating resources and tools for networked information retrieval (NIR). The Networked Information Retrieval Group is a cooperative effort of three major players in the field of NIR: The Internet Engineering Task Force (IETF), the Association of European Research Networks (RARE) and the Coalition for Networked Information (CNI), specifically tasked to collect and disseminate information about the tools and to discuss and encourage cooperative development of current and future tools.

The purpose of this report is to increase the awareness of NIR by bringing together in one place information about the various networked information retrieval tools, their developers, interested organisations, and other activities that relate to the production, dissemination, and support of NIR tools. The intention is to make this a "living document". It will be held on-line so that each section may be updated separately as appropriate. In addition, it is intended that the full document will be updated once a year so that it provides a "snapshot" report on activities in this area.

Whilst the NIR tools in this report are being used on a wide variety of information sources including files and databases there remains much that is currently not accessible by these means. On the other hand, the majority of the NIR Tools described here are freely available to the networked Research and Education community. Tools for accessing specialised datasets are often only available at a cost.

It should be noted that in many ways networked information retrieval is in its infancy compared with traditional information retrieval systems. Thesaurus construction, boolean searching and
classification control are issues which are under discussion for the popular NIR Tools but as yet are not in widespread use. However it should be said that, with the vast amount of effort that is currently going into the NIR field, rapid progress is being made. Much work is currently being done on expanding some of the NIR tools to include


Page 3

handling of multimedia information services. Progress has also been made in the discussions on classifying and cataloguing electronic information resources.

2. How the information was collected

The information contained in this report was collected over the network from the contacts for each NIR Tool or Group using two templates:

     - the NIR Tool Template, included in Appendix A;
     - the NIR Group Template, included in Appendix B.

The contents of these templates were discussed by the NIR WG in Boston (July, 1992) and subsequently on the email list. (See the Section on the NIR-WG for details of how to join this mailing list.) The initial draft report was discussed at the NIR Working Group in Washington (November, 1992) and updated and added to at subsequent WG meetings. Before the final submission as an RFC the individual templates were reviewed by independent reviewers from around the world. Their efforts are acknowledged in Section 9.

The NIR Tool template was used to collect the information necessary to identify and track the development of networked information retrieval tools. This template asked for information such as how and where to get the software for each NIR Tool, documentation, demonstration sites, etc. The main part of the template has been completed by the main individual responsible for the tool. Sections of the template (e.g., on clients) may have required completion by others.

The NIR Group template requested information on the aim and purpose of the group, the current tasks being undertaken, mailing lists, document archives, etc.

5. Overview of the types of NIR Tools

The following is an overview of major networked information retrieval (NIR) tools available on the Internet. There are many excellent books which discuss the Internet and NIR Tools in detail. Such books include "The Whole Internet User's Guide and Catalog" by Ed Krol and published by O'Reilly and Associates, Inc and "The Internet Guide for New Users" by Daniel Dearn and published by Meckler.

The number of these NIR tools is large and growing quickly. Certain techniques reappear regularly and seemingly different tools may perform similar tasks, allowing a simple classification of projects encompassing most of the existing tools and services.


Page 6

The classification presented here is only one possible ordering. The goal is to define in broad outlines what can be done with particular tools, realizing that users will always find novel unanticipated ways of applying them.

Interactive Information Delivery Services (Gopher, World Wide Web)

Basic Internet services such as electronic mail and anonymous FTP can be used to share information across the Internet, but neither allows simple browsing and neither is particularly easy for the newcomer to learn to use. Gopher and the World Wide Web (W3) are two recent developments that attempt to make it easier to distribute information over the Internet. Both allow the user to browse information across the network without the necessity of logging in or knowing in advance where to look for information.

The Gopher project was first developed at the University of Minnesota to provide a simple campus-wide on-line information system. Gopher represents information as a simple hierarchy of menus and files. It has limited capability to recognize different types of files, allowing, for example, the display of selected types of image files. Gateways to other services are provided (usually in a manner that is transparent to the user). The underlying Gopher protocol is simple, and has facilitated the creation of freely available clients for use on a variety of hardware platforms and operating systems. The more recent Gopher+ protocol adds the ability to provide documents in alternate forms (PDF, PostScript, RTF, Word). These features and the ease of installing and administering gopher servers has led to an explosive growth of gopher sites since its initial deployment. As of November 1993, there were over 2200 known servers.

World Wide Web relies on hypertext; formatted documents are displayed, and hypertext links within the document can be selected to travel from the current document to another. W3 allows a user to annotate documents (using hypertext links), provides gateways to other services, and has multimedia support (for example, on appropriate hardware platforms it can intermix text and images in a displayed document). There is a range of free W3 clients, supporting many environments. World Wide Web was originally developed at CERN for the High Energy Physics Community.

Gopher and WWW share a maintenance problem in that there is no automated way to update links to other documents when those documents are moved or removed.


Page 7

Directory Services (WHOIS, X.500)

Directory Service tools are intended to provide a lookup service for locating information about users (often referred to as White Pages), or services and service providers (Yellow Pages). For example, a White Pages service might be used to locate an electronic mail address, given a name and organization, while a Yellow Pages service could be used to locate an online library catalog or file archive site.

One of the first directory services deployed on the Internet was WHOIS, a simple White Pages service created to track key network contacts for the early DARPA-sponsored incarnation of the Internet. A number of sites currently operate WHOIS servers, based on a range of extensions and enhancements to the original model. WHOIS enjoys the advantages of simplicity and the presence of WHOIS client software on a preponderance of Internet-connected hosts. Work is underway on a more powerful protocol, known as WHOIS++, which is backwards-compatible with WHOIS.

The X.500 Directory Service is a much more ambitious Directory project that has been under development for a number of years under the aegis of ISO/OSI. Implementations, concerned primarily with White pages services, are available in the public domain and from commercial sources. There are LDAP based X.500 clients available for most major platforms, as well as a LDAP based gopher gateway to X.500.

Despite years of effort, there is still no single White Pages Directory Service for the entire Internet; Yellow Pages services remain even less well developed and deployed. The cost of setting up the service is one obstacle; maintaining the required databases is even more daunting.

Indexing Services (archie, Veronica, online library catalogs)

There are several Internet-based projects that build indexed catalogs of information to facilitate searching and retrieval. The first such services provided network access to library card catalogs, with more recent projects indexing network-based information.

archie:

The archie service began as a simple project to catalog the contents of hundreds of ftp-accessible online file archives. The archie service gathers location information, name, and other details describing such files and creates an index database.


Page 8

Users can contact an archie server and search this database for files they require.

The archie service is accessible through a range of access methods, including telnet, stand-alone client programs running on a user's own machine, gopher, WWW, or via electronic mail. The initial implementation of archie tracks over 2,100,000 filenames on over 1,200 sites around the world (as of November 1993). There are about 30 (geographically distributed) archie servers. Both commercial and freely available versions of the archie client software are available.

Work continues on extending the archie service to provide additional types of information. The latest version is being used to provide a prototype Yellow Pages service and directories of online library catalogs and electronic mailing lists.

Veronica:

Veronica arose as an attempt to do for the world of Gopher what archie did for the world of ftp. A central server periodically scans the complete menu hierarchies of Gopher servers appearing on an ever-expanding list (over 2000 sites as of November 1993). The resulting index is provided by a veronica server and can be accessed by any gopher client.

Online library catalogs:

A large number of libraries make their computerized library catalogs available over the Internet. Most are available through telnet sessions in which the user connects to a specific address and logs in using a specific login name. Some are also available through other tools, such as Gopher.

Text-based Indexing Services (WAIS)

WAIS:

Wide Area Information Servers (WAIS) is a system for indexing and serving information in a network-based environment. It is distinct from indexing tools such as archie and veronica in that it is used to index text-based target documents on a server, as well as descriptions of the contents of a server.

A WAIS server allows the administrator to set up an index of the documents (or resources) to be published. The user employs a WAIS client to attach to a particular WAIS server, and specifies a search pattern which is matched against the server's index. In


Page 9

early WAIS clients, searches are specified as simple natural- language queries; common ("stop") words are removed, and Boolean "ORs" are implicitly added between the remaining list of words. Matching documents are rank-ordered according to a simple statistical weighting scheme which attempts to indicate likely relevance. The user may choose to view selected documents, or further refine the search. The results of one search may be used to successively refine future searches ("relevance feedback"). Gopher clients can also access WAIS servers via a transparent gateway.

Both freely available and commercial versions of WAIS servers and clients are available. Current work is attempting to add Boolean expressions and proximity and field specifications to queries.

There are currently (as of November 1993) some 500 registered WAIS databases with an estimated 2000 additional databases that are not yet registered. There are approximately another 100 commercial WAIS databases.

ALEX

Date template updated or checked: 19th March, 1994

 ----------------------------------------------------------------------

 NIR Tool Name:      Alex

Brief Description of Tool:

OVERVIEW:

The Alex filesystem provides users and applications transparent read access to files in anonymous FTP sites on the Internet. Today there are thousands of anonymous FTP sites with a total of a few millions of files and roughly a terabyte of data. The standard approach to accessing these files involves logging in to the remote machine. This means that an application can not access remote files like local files. This also means that users do not


Page 10

have any of their aliases or local tools available. Users who want to use an application on a remote file first have to manually make a local copy of the file. There is no mechanism for automatically updating this local copy when the remote file changes. The users must keep track of where they get their files from and check to see if there are updates, and then fetch these. In this approach many different users at the same site may have made copies of the same remote file each using up disk space for the same data.

Alex addresses the problems with the existing approach while remaining within the existing FTP protocol so that the large collection of currently available files can be used. To get reasonable performance long term file caching is used. Thus consistency is an issue. Traditional solutions to the cache consistency problem do not work in the Internet FTP domain: callbacks are not an option as the FTP protocol has no provisions for this and polling over the Internet is slow. Therefore, Alex relaxes file cache consistency semantics, on a per file basis, and uses special caching algorithms that take into account the properties of the files and of the network to allow a simple stateless filesystem to scale to the size of the Internet.

USER'S VIEW:

To a user or application, Alex is just a normal filesystem. Any command that works on local files will work on Alex files. Since Alex is a real filesystem, nothing needs to be recompiled and no libraries are changed. Thus, users can apply all of their existing skills and tools for using files.

The user sees a filesystem with a hierarchical name space. At the top level (/alex) there are top-level Internet domains like "edu", "com", "uk", and "jp". Each component of the hostname becomes a directory name. Then the remote path is added at the end. If the user does a "ls /alex/edu/berkeley" he sees some machine names such as "ucbvax" and "sprite" and some directories on
berkeley.edu. From the "ls" it is not clear what is where. The user may or may not be aware of host boundaries.

INFORMATION PROVIDER'S VIEW:

Alex is implemented as a user level NFS server. NFS was chosen because it makes it easy to add Alex to a wide range of machines. Most machines can simply use the mount command.


Page 11

The model of usage is that there is one Alex server running at each institution (though this is not required in any way). Users mount the local server which caches files for users at that site.

Any information put into any anonymous FTP site becomes available via Alex.

 NIR Tool Name:                  archie

Brief Description of Tool:

The archie system is a tool for gathering, indexing and serving information from around the Internet. The current version serves a collection of filenames found at anonymous FTP sites, as well as a smaller collection of text descriptions for software, data and other information found at anonymous FTP archives. Additional databases are under development.

User's View:

Users run a client program to connect to an archie server and issue search commands to find information in an archie database. In the case of an anonymous FTP filename, this information can then be used to fetch the file directly from the archive site using the `ftp' command. To the user, archie could be seen as a `secondary source' of information which, because of the high cost of locating and serving, would not otherwise be available.

The user searches the archie databases through either a telnet session to a machine running an archie server, or by using a stand-alone client program (which uses the Prospero protocol for sending and receiving requests). There is also an email interface which allows users to send and receive search requests via electronic mail.

Freely available archie clients exist for most operating systems and can be fetched using anonymous FTP from most of the current archie servers. There are also gateways to the archie system from many other NIR tools, including Gopher, WAIS and WWW. An X.500 interface to archie is currently under development.

Information Provider's View:

There are two types of information providers who would be interested in archie. Primary information providers are interested in having a summary of the information provided by their service tracked by an archie server. Secondary service


Page 16

providers, or those sites wishing to provide a "value-added" service for the Internet can elect to run an archie server at their site to provide a useful service to users, to raise the profile of their institution on the Internet, or to provide market differentiation (for commercial service providers).

The archie system is of particular utility serving information where there are many sites to be searched and/or where the cost of searching each site is high.

For example, there are currently over 1,200 anonymous FTP sites on the Internet, and the number continues to grow. Searching for a specific filename at a single site may involve scanning hundreds, or even thousands of filenames. Thus, most operators of anonymous FTP archives welcome the fact that archie indexes and serves the names of all files available from each site tracked.

Information Types Supported:

The archie system allows the gathering and serving of arbitrary information types, although the current system serves only freeform text and a dedicated text format for filename listings. Internally, the archie system now supports a WAIS search engine and frontends for Gopher, WWW and WHOIS++ for accessing archie information through Gopher clients is now being tested. Additional collections of information to be served by the archie software will be announced.

Description:

This mailing list is for people who are involved in the Internet Anonymous FTP Archives Working Group of the IETF. This group was involved in standardizing the encoding of information at anonymous FTP archives and thus is of interest to operators and users of the archie system. It came to completion in November, 1992 and produced two documents which have been presented to the IETF as informational RFCs.

Protocols:

What is supported:

The current archie system clients use the Prospero protocol for communication with the search engine on the archie server. Freely available clients are available which include source to perform this communication for those wishing to implement additional clients.

The archie server is capable of building arbitrary databases, using arbitrary search and access engines and the current release ships with the public domain implementation of WAIS. We expect future archie servers to serve information using this protocol. The current server system assumes the TCP/IP protocol suite is available, and in particular the ftp protocol for data gathering.

The archie system can be accessed through systems operating the Gopher, WAIS and WWW (HDDL) protocols. A gateway from the X.500 system is under development.


Page 20

What it runs over:

The Prospero protocol implementation runs over its own implementation of a reliable datagram protocol based upon UDP. Data gathering runs over the TCP/IP protocol suite.

Other NIR tools this interworks with:

Prospero, Gopher, WAIS, WWW.

Future plans:

The archie system became a commercial product in October, 1992, marketed by Bunyip Information Systems Inc. The company plans to market additional data gathering modules to allow the server code to build additional types of databases. Work is also underway to integrate extensions to WHOIS to allow the building and maintaining of White Pages (names) directories. The company is also working on other Internet information tools that will work with the archie system.

  Latest version number:          archie 3.1

Brief Scope and Characteristics:

This is the commercial inmplementation of the archie system, replacing a version done as a Masters project at McGill University during the period 1990-1992. It comes with an archie telnet client that offers a number of minor improvements over earlier versions. Additional releases, with a number of additional improvements, are planned in the coming months.

NIR Tool Name: Internet Gopher

Brief Description of Tool:

The Internet Gopher protocol is a client/distributed-server document search and retrieval protocol originally developed at the University of Minnesota. Gopher was originally created as a fast, simple, distributed, campus-wide information search and retrieval system; ease of use and implementation has made Gopher increasingly popular on the Internet. Since its original release, many folks on the Internet have contributed to its growth, submitting patches, servers, clients, and linking their local servers into the worldwide network of Gopher servers. Gateways exist to seamlessly access a variety of non-Gopher services such as ftp, WAIS, USENET news, Archie, Z39.50 (1992 rev), X.500 directories, Sybase and Oracle SQL servers, etc. In addition, an "archie for gopherspace" called Veronica (very easy rodent-oriented net-wide index to computerized archives) has been developed at the University of Nevada. Veronica makes it easy to search for items in gopherspace by title.

The gopher protocol is often described as "fiercely simple"; it is connectionless (stateless), and uses TCP reliable streams. A client connects to a server using TCP, and sends a one-line text "selector string". The server responds by returning the item (a file, a directory listing, or a link to some other service) corresponding to the selector string and immediately closing the connection. Items in directory listings are returned as a series of lines terminated by carriage-return line-feed. Each item (line) is defined by a one- character tag to specify the item type, a display string or item-name that the client should display to the user, and a number of tab delimited fields to specify the selector string, host domain name and port number. Because of its simple and connectionless nature, gopher servers make very minimal demands on their host machines and gopher clients are extremely easy to implement.

The users view the Gopher world as a series of networked hierarchical directories much like a familiar filesystem. However, the links define a graph rather than a simple rooted tree. Links in the Gopher graph may define services other than simple files or directories; these include cso (qi) servers, telnet sessions, links to other


Page 28

gopher servers, and links to gateway servers.

The information provider's simplest view is that files and directories below a certain root directory on their machine are all visible and available for retrieval by gopher clients. More features like long names, item types, links, and gateway services are available to the more sophisticated information provider.

Servers and clients run on most popular hardware, including Macs, UNIX boxes, PC-DOS boxes. The Internet Gopher name is copyright (c) 1991-1992 by the University of Minnesota. The Internet Gopher protocol is described in an informational RFC (1436) available at better RFC archives everywhere. Extensions to the base gopher protocol allow for associating meta-information with gopher items, alternate views of documents (i.e., text, postscript, rtf, etc.) and electronic forms. Collectively, these extensions are referred to as Gopher+. Gopher+ is upward compatible with the orginal gopher protocol. The gopher software may be retrieved from numerous Gopher or FTP archive sites, including the University of Minnesota Gopher server, the Info-Mac Archive Gopher server, and by anonymous FTP from boombox.micro.umn.edu and sumex-aim.stanford.edu. As of December 1993, about 1/3 of the approximately 4800 Gopher servers on the internet support Gopher+.

NETFIND

Date template updated or checked: 1 March, 1994

     Email address:     schwartz@cs.colorado.edu

 -----------------------------------------------------------------------

NIR Tool Name: Netfind

Brief Description of Tool:

Given the name of a person on the Internet and a rough description of where the person works, Netfind attempts to locate information about the person. People can be specified by first, last, or login name. Their place of work can be described by name and/or the
city/state/country.

Netfind provides textual information about people, when it is able to locate such information. It is not a directory in the usual sense of the word. Rather, it searches for people using a number of Internet services and heuristics about how to locate user information. Because of the techniques it uses, Netfind can locate information about more people than any other Internet user directory - over 5 million people in over 9,000 domains worldwide when last measured.

You can use the University of Colorado Netfind server by telnet to bruno.cs.colorado.edu: login as "netfind" (with no password). Help screens providing more detailed instructions and technical information are available there. There is currently no way for non- Internet users to access Netfind (e.g., using an email interface).

  Telephone:            Declined.  (Note: Netfind is currently a
                        volunteer service.  We do not have staff

 -----------------------------------------------------------------------

Help Line:

There are an increasing number of Netfind servers being set up at various Network Information Centers (including the U.S. Internic). However, since Netfind is provided as a volunteer service at this time, there is no help line.

 -----------------------------------------------------------------------

Related Working Groups:

Gopher, NIR, IIIR, IRTF-RD.

 -----------------------------------------------------------------------

Sponsoring Organisation / Funding source:

None. Netfind was originally a research prototype. It is offered as-is, on an unsupported basis. From time to time the original developers make improvements, but it is not currently funded.

Protocols:

  What is supported:    NVT ASCII.  At present no formal protocol is
                        used. We are currently implementing a client/
                        server protocol, which will allow better clients
                        and more efficient servers.

  What it runs over:    TCP/IP.

Other NIR tools this interworks with:
Finger, Gopher, PH, SMTP, USENET news, UUCP maps, Various NIC databases, Various service logs, WAIS, WHOIS, X.500, DNS

Future plans:

Many. Telnet to the server and see the "Future Directions" menu under the "Frequently Asked Questions" help menu.

In addition to the above list, we are currently exploring possibilities to integrate the Netfind seed database gathering mechanisms into the Fremont framework, to make the process more scalable, and to support other types of information (e.g., to help with mapping the Internet).

NIR Tool Name: Prospero

Brief Description of Tool:

The Prospero directory service supports a user centered view of files scattered across the Internet. It can be used to organize references to files as if they were on your local system, without the need to physically move them.

Prospero provides access to existing directories and indices that can be used to find files of interest that are available from Internet archive sites. Among the indices available is the archie database and a gateway to all Gopher menus, files, and searches. We hope to have WAIS indices and World Wide Web documents online in the near future.

Prospero also provides a mechanism to make directories and indices available to end-users and applications in a format that allows information from different sources to be integrated into a coherent whole.

Prospero does not interpret the data that it organizes. It does provide mechanisms to retrieve the data, but the display and use of the data is up to the user's application. Prospero is intended to serve as infrastructure that integrates information from a variety of sources and supports a variety of user applications.

Prospero allows fine grained authorization of requests to all objects, including directories and indices. Prospero supports the authentication of clients through four mechanisms: (a) simple client assertion of the user's identity; (b) a trusted port mechanism similar to that used by the Berkeley UNIX R commands; (c) a simple cleartext passwording mechanism; (d) Kerberos (version 5). The maintainer of an ACL chooses which of these mechanisms he or she wishes to accept as proof of the client's identity.

Via Prospero: /releases/prospero/prospero.tar.Z, in the
"#/INET/EDU/ISI/GUEST/prototype" virtual system.

Note that the name prospero.tar.Z refers to the most stable release (currently Beta version 5.1). If you want the latest version of the server (which includes the Gopher gateway), you should retrieve it by version number; the name for the latest version is
prospero-alpha.5.2.tar.Z

Location of more information:
Contained within the release.

Latest version number:
Alpha Version 5.3

Brief Scope and Characteristics:

The server allows the maintainer to make directory information available about selected portions of the server's filesystem, such as anonymously FTPable files. The server also is used to publish information from other databases, such as Archie. The server also allows users and maintainers to store their own customized organizing views of the namespace. Release Alpha.5.2 of the server includes a gateway feature which treats all Gopher servers as a Prospero database.

Approximate number of such servers in use:

50

General comments:

Future plans:

We have a prototype NFS server that makes Prospero queries, but it is not yet ready to release. We plan to develop a gateway similar to the existing Gopher gateway feature for World Wide Web. There is also active work being done on exporting WAIS indices through Prospero in a way similar to the way the archie database is exported.

Latest Version number:
Alpha Version 5.2

Brief Scope and Characteristics:

We provide two client interfaces. The older one is a command-line client, which can be configured to use the same syntax to navigate through the Prospero namespace that a user uses to navigate through the UNIX filesystem. ("cd", "ls", etc.) The newer one is a menu- based file and directory browser similar to the UNIX Gopher client.

General comments:

Archie clients also make queries in the Prospero namespace, so all Archie clients are Prospero clients too. They are better described in the Archie report.

Future plans:

We are working on enhancing the menu browser client to allow users to remotely customize and update virtual systems. We plan to develop a Prospero hypertext browser.

 -----------------------------------------------------------------------

Demonstration sites:

A guest virtual system is available on PROSPERO.ISI.EDU. However, to use it, you must compile the Prospero command-line client on your own machine. Instructions for using it come with the Prospero distribution.

For the readers of this report, this is the first paper you probably want to read about Prospero. This paper describes how Prospero can be used to integrate internet information services, including Gopher, WAIS, Archie, and World Wide Web. The paper was
presented at INET'93 in August.

This is the first paper we give to more general computer science audiences to read. It's also a good first paper to look at. It gives a good overview of Prospero and what it does. It also describes a bit about the Virtual System model, of which Prospero is a prototype implementation. Describes what Prospero does, not how it does it.

This paper describes the reasons that operating systems need to support closure, that is they need to make it clear which name space is to be used when resolving names. While closure is one of the important features of Prospero, the concept should be applied in other operating systems too.

This is Clifford Neuman's Ph.D. Dissertation. It is currently the definitive work on Prospero and the Virtual System Model. Includes an obsolete version of the Prospero User's Manual and of the Prospero Protocol Specification.

 -----------------------------------------------------------------------

Other Information:

We provide three documented library interfaces to Prospero in order to make client writing easy.


Page 73

The PFS and PCOMPAT libraries are documented in the library reference manual. The PFS library allows one to directly make Prospero requests and parse the results and to manipulate Prospero objects as abstractions. The PCOMPAT library is an interface to the PFS library which uses the same interface as the UNIX filesystem; one can link many existing programs with the PCOMPAT library in order to get it to resolve names in the Prospero namespace. It is not as portable as the PFS library and does not provide as much functionality.

The third library interface is the menu-browser API library. It is documented in the menu-based browser API manual and is used by our menu-based browser.

NIR Tool Name: veronica

Brief Description of Tool:

veronica: Very Easy Rodent-Oriented Net-wide Index to Computerized Archives.

veronica is the comprehensive title-index of the world's gopher servers. Because of veronica, the Gopher web is a search-and- retrieval system as well as a browsing system. veronica is popular because the ubiquitous Gopher client can both access the search server, and provide immediate access to the discovered resources. Taking advantage of Gopher's linked menus, and of the policy of open access at most gopher sites, veronica finds and indexes almost all items on publicly-accessible gopher servers.

As of February, 1994, veronica holds indexes to more than 3200 gopher servers on approximately 2500 internet hosts. In February 1994 the public-access veronica sites served an estimated 1,200,000 queries. Most queries are resolved in less than twenty seconds. Eight server sites offer searches to the internet community, and several other institutions run servers for internal access.

veronica is easily accessed via any Gopher client. It offers various types of searches, ranging from single-keyword searches to boolean queries of indefinite complexity.

A veronica search originates with a user's request for a search, submitted from a gopher client. The searches may include boolean operators ( AND, OR, NOT, and parentheses ) and several options to control the number of items returned, and to restrict the search to certain gopher types. The result of a veronica search is a set of gopher-type data items, which is returned to the gopher client as a gopher menu. Each item on this menu contains the user's desired keyword or keywords in the item title.

The user can access any of the gopher items by selecting from the returned menu. Items on this menu may be drawn from many gopher servers. Because veronica is accessed through gopher clients, it provides immediate access to all types of data supported by the


Page 75

gopher protocol and the client implementation.

The veronica service comprises two functions:

1) Harvesting menu data from gopher servers, and preparing it for use;
2) Offering searches of that database to gopher clients.

These two functions are not necessarily provided by the same host computer. Currently collection and preparation of data are done at University of Nevada, and datasets are distributed to the other veronica servers.

The veronica service infrastructure has been fairly stable since July, 1993, with eight server sites offering searches for the internet community (March 1994). These servers are supported by the participating institutions: NYSERNET, PSI, SERRA, CNIDR, University of Koeln, SUNET, University of Bergen and the University of Nevada System Computing Services. Several additional servers offer searches with access limited to internal users; in this class are servers at MSU, SUNET, and the Australian University system.

An auxiliary tool to build a locally held menu of Public available has been created. Called "maltshop", it has been distributed since January, 1994. It appears that maltshop is rapidly being accepted, but its long-term effect on loading of the servers may be problematic.

                                  veronica-docs/

  Latest version number:        0.6.5
  Next planned version:         0.7b   (March 1994)

Brief Scope and Characteristics:

   Two modules:    a data-collection module and a data-server module.

1. Data-collector runs on any Unix computer that does TCP
and compiles perl. This has not been distributed yet. Data collection, data preparation, and indexing are being done at veronica.scs.unr.edu. The harvester "walks" all advertised gopher servers, and any newly-discovered servers. Almost all redundant links are removed, leaving the ( hopefully ) canonical reference for each item. Indexes are built at Nevada, and the indexed dataset is distributed to server sites.
2. Server module.
Servers run on unix computers and answer to gopher-type-7 requests. Boolean keyword logic is implemented. See file "how-to-compose-veronica-queries". Several options allow retrieval of items with specified gopher-types, retrieval of a file of links containing the search results, and override for the default limit on number of results returned, which is 200 items.

Server software runs on most flavors of unix, requires dbm and perl, and requires about 1.4 GB of data on disk, with considerable /tmp space available.

Server software is available to any site which wants to run a server. Server sites are encouraged to offer the service to the net at large.

Approximate number of such servers in use: twelve.

Maltshop builds a menu of Public Gopher Servers for the local gopher menu.

General comments:

Basic veronica service has been fairly stable since July 1993. Indexing is quite efficient, and most queries are resolved in ten seconds or quicker. More than 1,000,000 queries were resolved in February, 1994.

Though veronica is well-accepted at this level of service, we are undertaking significant upgrade efforts during Winter 93-94.

 NIR Tool Name:   WAIS

Brief Description of Tool:

WAIS - The Wide Area Information Servers system - is an electronic publishing software set which allows you to search out and retrieve multimedia information from databases anywhere in the world. WAIS databases may be accessed by WAIS, gopher, and WWW clients (such as Mosaic), and via online services such as Delphi and America OnLine. WAIS software includes user interfaces for most platforms, and server software that provides automatic indexing of databases.

WAIS was developed by Thinking Machines Corporation of Cambridge, Massachusetts in collaboration with Apple Computer, Inc., Dow Jones & Company, and KPMG Peat Marwick. With over 100 databases and 5,000 users worldwide, WAIS is rapidly becoming a standard for information distribution within the Internet environment.

WAIS is a client-server application. Most of the clients remain freely available with a few exceptions. WAIS, Inc. develops and sells commercial versions of WAIS and the Clearinghouse for Networked Information Discovery and Retrieval (CNIDR) develops freeWAIS, a version free for distribution and use. A few freely distributable versions remain available from Thinking Machines, Inc. and other organizations.

What does WAIS do?

WAIS allows multimedia information to be stored anywhere on any platform. Using your interface of choice, WAIS enables you to find personal, corporate and public information. The information is accessible regardless of format: text, formatted documents, pictures, spreadsheets, graphics, sound, or video.


Page 84

WAIS recognizes natural language queries. The search and retrieval of relevant information is made using your native language. To date, we have used English, French, Italian, and Latin! The most relevant documents, regardless of size, can be sent back to the server in their entirety to further refine your search (telling the server, "Find me more like this document.") Proven searches can be automatically repeated, monitoring and alerting you to new information as it becomes available.

How does WAIS work?

WAIS uses a single computer-to-computer protocol (NISO Z39.50- 1988). Each WAIS server reads your question and based on its words, searches the full text of the database for the most relevant documents, and ranks them using automatic word weighting. Servers need not fully understand your query; the retrieval process is based on a search method called relevance feedback.

NIR Tool Name: Whois

Brief Description of Tool:

As currently defined, NICNAME/WHOIS services is a TCP transaction based query/response server, running on a few specific central machines, that provides netwide directory service to internet users. Since the WHOIS service was defined in 1985, it has evolved into a distributed service.

The InterNIC Registration Services is located at Network Solutions, Inc., Herndon, VA, and is funded by a cooperative agreement from the National Science Foundations to provide assistance in registering networks, domains, asn's, and other entities to the Internet community via telephone, electronic mail, and U.S. postal mail.

Databases and information servers of interest to network users are provided, including the WHOIS registry of domains, networks, asn's and their associated poc's. Gopher and Wais interfaces are also available for retrieving information and accessing whois. Online documents maintained at registration services include registration related rfc's, registration templates, and various netinfo files. Many of the online files are available through our automatic mail service, MAILSERV@RS.INTERNIC.NET. Whois queries can also be directed to rs.internic.net. From a host, use the TELNET program to connect to host RS.INTERNIC.NET. When greeted by the Registration host, type "WHOIS" and press RETURN.

MAILSERV@RS.INTERNIC.NET is an automated service provided by InterNIC Registration Services. It allows access to documents and information via ordinary electronic mail. This is especially useful for users who do not have access to the NIC via a direct Internet link, such as users of BITNET, CSNET and UUCP sites.

To use the mail service, send a mail message to
MAILSERV@RS.INTERNIC.NET. In the SUBJECT field, request the type of service you wish followed by any needed arguments. The message body is normally ignored. Large files will be broken into smaller separate messages. The information you request will be sent back to you as soon as possible.

   WHOIS xxx       Returns information about xxx from the WHOIS service.
                   Use "WHOIS HELP" for information on how to use WHOIS.

The MILNET Network Information Center, maintains the central NICNAME database and server, providing online look-up of individuals, network organizations, MILNET nodes, and other information of interest to those involved in management of the Internet. Whois queries can be sent to nic.ddn.mil.

 NIR Tool Name:            World-Wide Web

Brief Description of Tool:

The WWW project merges the techniques of networked information and hypertext to make an easy but powerful global information system. W3 uses the concept of a seamless information space (the "web"), in which all objects including those accessed by earlier protocols (wais, gopher, ftp, etc.) exist.

The project allows information sharing within internationally dispersed teams, and the dissemination of information by support groups. Originally aimed at the High Energy Physics community, it has spread to other areas and attracted much interest in user support, resource discovery and collaborative work areas. It is currently the most advanced information system deployed on the Internet.

READER VIEW

The WWW world consists of documents, and links. Indexes are special documents which, rather than being read, may be searched. The result of such a search is another ("virtual") document containing links to the documents found. A simple protocol (" HTTP ") is used to allow a browser program to request a keyword search by a remote information server.

The web contains documents in many formats. Those documents which are hypertext, (real or virtual) contain links to other documents, or places within documents. All documents, whether real, virtual or indexes, look similar to the reader and are contained within the same addressing scheme.

To follow a link, a reader clicks with a mouse (or types in a number if he or she has no mouse). To search and index, a reader gives keywords (or other search criteria). These are the only operations necessary to access the entire world of data.


Page 104

INFORMATION PROVIDER VIEW

The WWW browsers can access many existing data systems via existing protocols (FTP, NNTP) or via HTTP and a gateway. In this way, the critical mass of data is quickly exceeded, and the increasing use of the system by readers and information suppliers encourage each other.

Providing information is as simple as running the W3 server and pointing it at an existing directory structure. The server automatically generates the hypertext view of your files to guide the user around.

To personalize it, you can write a few SGML hypertext files to give an even more friendly view. Also, any file available by anonymous FTP, or any internet newsgroup can be immediately linked into the web. The very small start-up effort is designed to allow small contributions. At the other end of the scale, large information providers may provide an HTTP server with full text or keyword indexing. This may allow access to a large existing database without changing the way that database is managed. Such gateways have already been made into Oracle(tm), WAIS, and Digital's VMS/Help systems, to name but a few.

The WWW model gets over the frustrating incompatibilities of data format between suppliers and reader by allowing negotiation of format between a smart browser and a smart server. This should provide a basis for extension into multimedia, and allow those who share application standards to make full use of them across the web.

This summary does not describe the many exciting possibilities opened up by the WWW project, such as efficient document caching. The reduction of redundant out-of-date copies, and the use of knowledge daemons. There is more information in the online project documentation, including some background on hypertext and many technical notes.

GETTING STARTED

You can bootstrap yourself into the web by telnetting to info.cern.ch (no user or password). You can try a full screen interface "Lynx" by telnetting to ukanaix.cc.ukans.edu, login in as "www". You can also find out more about WWW in this way. These are the least sophisticated browsers -- remember that the window-oriented ones are much smarter! It is much more efficient to install a browser on your own machine, and you have many more facilities.


Page 105

If you have an X-windows based workstation, PC or Mac just FTP to FTP.NCSA.UIUC.EDU and get the binary of NCSA's "Mosaic" browser in directory /Web/Mosaic-binaries. Download it, uncompress it, set it executable, and run it. It will tell you all you need to know.

Mosaic is now available for PCs and Apple Macs.

If you have an MSDOS machine with Windows, you could try the "Cello" browser from FATTY.LAW.CORNELL.EDU in directory

      /pub/LII/Cello.

The line mode browser is currently available in source form by anonymous FTP from node info.cern.ch [currently 128.141.201.74] if you take both files

                /pub/www/src/WWWLibrary_v.vv.tar.Z.
                /pub/www/src/WWWLineMode_v.vv.tar.Z.

(v.vv is the version number - take the latest.)

Also available is a hypertext editor for the NeXT (in

   /pub/www/bin/next), the MidasWWW and ViolaWWW browsers for X11, an
   alpha-test Mac browser, and and a basic server
   (/pub/www/src/WWWDaemon_v.vv.tar.Z).  Documentation, including the
   latest list of software available , is readable using www.  A plain

X.500 White Pages

Date completed or updated: 10 March, 1994

  By: Name:          Chris Weider
      Email address: clw@bunyip.com

 -----------------------------------------------------------------------

NIR Tool Name: X.500

Brief Description of Tool:

X.500 is an international standard designed to provide a distributed
global directory service. It is primarily used today to provide 'White Pages' services, although other types of services which have directory components (automated mail aliasing, for example) are beginning to be run over X.500. In addition to information about people and organizations, the Directory also contains a pilot K-12 Directory, pilot Information Resource information, and some other non-White Pages information. X.500 contains a number of security features, which are implemented on different paradigms in the various servers.

User's View:

Users (either human or electronic) run a client program to connect to a local X.500 server. Since X.500 is distributed, it appears that the entire global X.500 directory is available from the local server. From this server connection, the user can add, delete, or modify information held by the Directory, or issue powerful search commands to locate individuals or other information.

The first solid version of the X.500 protocol was released in 1988, and has been the subject of much research in the past 5 years. Consequently, there are a large number of clients, for almost every platform, and a healthy number of servers. There are mail interfaces to some parts of the X.500 directory, and there is a X.500 to Gopher gateway. An X.500 interface to archie is currently under development, as well as an X.500 to WWW interface.

Information Provider's View:

X.500 provides a set of mechanisms to allow distributed location
of, maintenance of, and access to a large set of data. However, current servers force a hierarchical view on the location of the data, so it may not be suitable for all applications. Also, the X.500 directory is today unable to provide access to information at a rate which would allow 'real-time' applications (such as


Page 118

keeping routing information in the directory).

Also, there is a great effort underway to reduce the startup costs of X.500 access by providing a lightweight X.500 access protocol for client-server applications. This work is detailed in RFC 1487:

"Lightweight Directory Access Protocol", by Yeong, Howes, and Kille. This protocol is expected to make the cost of entry for a service provider much less that it has been.

Information Types Supported:

X.500 allows information to be served in an attribute:value
paradigm, with related attributes grouped into 'objects'. Each entry in the directory can be described by multiple objects. Attributes can have values which are text strings, dereferenceable file names, or text-encoded photographs, and experimentation is underway to keep digitally encoded sounds in the directory.

Description of main group:

The Coalition for Networked Information was founded in March 1990 to help realize the promise of high performance networks and computers for the advancement of scholarship and the enrichment of intellectual productivity. The Coalition is a partnership of the Association of Research Libraries (ARL), CAUSE, and EDUCOM. ARL is dedicated to equitable access to, and effective use of, recorded knowlege in support of teaching, research, scholarship, and community service, and CAUSE and EDUCOM are dedicated to different aspects of the introduction, use, and management of information technology and related resources in research and education in general and higher education in particular. The Coalition pursues its mission with the


Page 124

assistance of a task force that provides a common vehicle by which more than 190 institutions and organizations are exploring a shared vision of how information management must change in the 1990s to meet the social and economic opportunities and challenges of the 21st century. Members of the Coalition Task Force include, among others, higher education institutions, publishers, network service providers, computer hardware, software, and systems companies, library networks and organizations, and public and state libraries. A truly diverse collaboration of institutions and organizations.

Description of main group:

This group recognizes the need for open systems, standards, and therefore, interoperable products and services based upon a distributed architecture of servers that draw upon a common or at least comparable set of data elements. It is creating a (printed and networked) directory of directories and resource information services that provide qualitative (consumer) as well as descriptive information. The group supports the Library of Congress effort to enhance the MARC formats to account for the cataloging requirements of networked resources and services, and the National Science Foundation effort to procure a new NSFNet Network Information Center.

Description of main group:

(from ARL Newsletter #164 -- September 9, 1992)

The Coalition's TopNode Project is creating a directory of directories, catalogs and aids of networked information resources, services and tools. The project is intended to facilitate the network navigational duties, responsibilities and tasks of staff in libraries, computer centers, networking offices and other similar operations. The primary product of the TopNode project will be a set of records describing these networked information resources, records that can be loaded into a wide range of database management systems.

Based on their response to a Call for Statements of Interest and Experience, Indiana University and Merit Network, Inc. were chosen to lead the development effort on the Coalition TopNode project. Pete Percival, Manager, Academic Information Environment at Indiana University and Craig Summerhill, Coalition Systems Coordinator, have completed the design for the database structure which is being built on the Coalition's Internet fileserver using BRS/SEARCH. Based on earlier work of the leaders of the Directories and Resource Information Services Working Group, George Brett II of the University of North Carolina General Administration and Peggy Seiden of Skidmore College Library, Percival and Summerhill have developed a data structure that they believe to be both flexible and responsive to the needs of the many interested parties who have been consulted.

Under the direction of Gary Charbonneau of the Indiana University Libraries, records are being created and prepared for loading. A


Page 135

thesaurus of added descriptor terms is being maintained. As of mid-August 1992, close to 200 records had been verified and had received descriptive cataloging.

When the database is complete, libraries will be alerted and encouraged to mount the TopNode records into their online catalogs. Records will be available from the Coalition. In addition, MERIT will use the TopNode database in an experiment to test the viability of the X.500 directory format standard for providing yellow pages-type services (e.g., with subject access). After its initial release, the database will be maintained by Indiana University libraries on the Coalition server; BRS has assisted in the development of procedures for online data entry.

Description of main group:

Several user-friendly client-server software tools have been developed recently for locating and retrieving information published on computer platforms reachable over wide-area data communications networks like the Internet. Among them, freeWAIS (freely available wide-area information system), the Internet Gopher, archie, and the WorldWide Web (WWW) have become popular. freeWAIS, archie, and Gopher indicate where information of interest is likely to reside and then assist the user in locating specific information. WWW permits a user to thread a path through the network by selecting tagged hypertext items.

While focused on the evolution of wide-area information retrieval systems, the Clearinghouse for Networked Information Discovery and Retrieval (CNIDR) works closely with developers of other tools toward providing compatibility, consistency, and, to the extent possible, convergence of the tools.

Specific activities are to provide a central focus and forum for networked information discovery and retrieval (NIDR) tools and to minimize the divergence of individual implementations by
providing a repository for the collection, evaluation, and distribution of protocol-compliant releases and enhanced
versions.

CNIDR participates in standards and policy associations such as the Internet Engineering Task Force and the Coalition for
Networked Information, with the goal of increasing consensus among developers and exploring appropriate uses of networked


Page 138

information. CNIDR also actively promotes the use of networked information discovery and retrieval tools at many national and international conferences to inform and educate implementors and end users.

NIR Group Name: Integration of Internet Information Resources (IIIR)

Sponsoring Organisation: Internet Engineering Task Forces (IETF)

Working subgroups: None

Description of main group:

The IIIR group was chartered in September 1992 to facilitate interoperability between and integration of the various Internet information services (Archie, Gopher, WAIS, etc.), just as the IETF was founded to facilitate the integration of various LANs running different protocols. It will develop, specify, and align protocols to integrate the services into a single "virtually unified information service" (VUIS).

Also, where necessary for interoperability, IIIR will create technical documentation for protocols used for information services in the internet.

Membership is open, and is not limited to IETF attendees. A full charter for this group is available via anonymous FTP from ds.internic.net as ietf/iiir/iiir-charter.txt

NIR Group Name: Networked Information Retrieval Working Group (NIR-WG)

Sponsoring Organisation: Internet Engineering Task Force (IETF) and

RARE (Association of European Research Networks)

 Working subgroups:     None

Description of main group:

There are many organizations and associations that have begun to focus on the proliferating resources and tools for networked information retrieval (NIR). The Networked Information Retrieval Group will be a cooperative effort of three major players in the field of NIR: IETF, RARE, and the Coalition for Networked Information (CNI) specifically tasked to collect and disseminate information about the tools and to discuss and encourage cooperative development of current and future tools such as the archie servers, the Wide Area Information Servers (WAIS), the Internet Gopher, and the WorldWide Web (WWW).

The NIR Working Group intends to increase the useful base of information about networked information retrieval (NIR) tools, their developers, interested organizations, and other activities that relate to the production, dissemination, and support of NIR tools.

Membership is open and is not limited to attendees of the quarterly IETF meetings; the mailing list is open to all. The NIR-WG charter is available via anonymous ftp from the various IETF repositories as nir-charter.txt.

Goals:

To disseminate information about NIR tools and those groups working on them. The information in the NIR Status report will be updated and new entries added as appropriate once per year. This report will be submitted as an RFC.

Current work includes discussing the criteria for evaluating the major NIR tools available.

 NIR Group Name:    Uniform Resource Identifiers (uri)

Sponsoring Organisation: Internet Engineering Task Forces (IETF)

 Working subgroups:    NONE

Description of main group:

The Uniform Resource Identifiers Archives Working Group is chartered to define a set of standards for the encoding of system independent Resource Location and Identification information for the use of Internet information services. There are three classes of information being standardized in this group:

1) Uniform Resource Locators (URLs), which specify a standardized method for encoding location and access information to resources across multiple information systems,

2) Uniform Resource Names (URNs), which specify a standardized method for encoding a unique resource identifier for a given content, and

3) Uniform Resource Citations (URCs), which specify a standardized method for encoding information about a given instantiation of a content.

The URLs allow an information service to give a user access and location information for a resource. The URN allows an information service to determine if the contents of two information resources are the same or not. The URC allows an information service to select which of a number of different encodings of a resource are appropriate for a given user's retrieval capabilities, and may contain such things as file size and compression techniques.

Membership is open, and is not limited to IETF attendees. A full charter for this group is available for anonymous FTP from ds.internic.net as /ietf/uri/uri-charter.txt

NIR Group Name: Whois and Network Information Lookup Service (WNILS)

Sponsoring Organisation: Internet Engineering Task Force (IETF)

Working subgroups:
Name of subgroup:
Mailinglist-Address: ietf-wnils@ucdavis.edu

Description of main group:

This description is the current WNILS-WG charter.

The Network Information Center (NIC) maintains the central NICNAME database and server, defined in RFC 954, providing online look-up of individuals, network organizations, key nodes, and other information of interest to those who use the Internet. Other distributed directory information servers and information retrieval tools have been developed and it is anticipated more will be created. Many sites now maintain local directory servers with information about individuals, departments and services at that specific site. Typically these directory servers are network accessible. Because these servers are local, there are now wide variations in the type of data stored, access methods, search schemes, and user interfaces. The purpose of the Whois and Network Information Lookup Service (WNILS) working group is to expand and define the standard for WHOIS services, to resolve issues associated with the variations in access and to promote a consistent and predictable service across the network.

Goals and Milestones:

  Done    Review and approve the charter making any changes deemed
          necessary. Examine the particular functional needs for
          expanded whois directory service. Begin work on a framework
          for recommendations.  Assign writing assignments for first
          draft of document.

12/1/93 Submit the Whois and Network Information Lookup Service Recommendations document to the IESG as an Internet Draft.

 -----------------------------------------------------------------------

NIR Group Name: Internet Research Task Force Research Group on Resource Discovery and Directory Service (IRTF-RD)

Sponsoring Organisation: Internet Society

Working subgroups: None

Description of main group:

The IRTF-RD group is focused on problems of scale that will arise in resource discovery systems in the next 3-5 years. We divide these scaling problems into three dimensions: volume of information, size of the user base, and information diversity.

Our goal is to explore techniques for dealing with these problems through a set of interrelated prototypes demonstrating advances in each of these dimensions. Briefly, our current approaches are:

     - deal with information diversity through a coordinated set
       of techniques to gather, transform, and manage entropy of data
     - deal with user scale through large scale replication
     - deal with information volume using a combination of
       views, space efficient indexing, and customization w.r.t.
       vocabulary, search methods, and personal user history
  We expect these approaches to evolve significantly over time.

Membership of this group is closed. We will consider new members, with two constraints. First, the group must be kept small and focused to make substantive progress - at most 4 or 5 members seems appropriate at this time. Second, prospective members must be active resource discovery researchers, who will bring clear strengths to the group. Prospective members should send a vitae and a one page position paper describing what they propose to do to advance the group's efforts, addressed to the group chair.

The group currently consists of:
Mic Bowman (Transarc, Inc.)
Peter Danzig (University of Southern California)
Udi Manber (University of Arizona)
Mike Schwartz (University of Colorado - Boulder; chair)

NIR Group name: Z39.50 Implementors Group

Description of main group:

The Z39.50 Implementors group (ZIG) is a volunteer organization consisting of representatives of most of the organizations in the United States and Canada that are actively engaged in implementing the Z39.50 protocol. This includes the United States Library of Congress, The National Library of Canada, the major bibliographic utilities, many library automation vendors, and other information service providers. The group is a volunteer effort whose meetings are open at no charge to all. The group meets about 3 times a year and conducts its activities extensively on its mailing list which is also open to any interested party.

The group was originally formed to deal with interoperability issues among the Z39.50 implementations that were beginning to emerge in 1989 and 1990 but the group has since expanded its role and has now become the primary forum in which new features and versions of the Z39.50 are developed.

Brief Description of the Z39.50 Protocol

Z39.50 is a US ANSI standard protocol for information retrieval. It uses a client server model that allows clients ( or origins in Z39.50 terminology) to search servers (targets in Z39.50 usage) and retrieve records from remote databases. The type and format of the data retrieved is not constrained by the protocol but is agreed to by the origin and the target. There is a mechanism that allows popular record syntax's to be registered and then referred to by well known identifiers. Z39.50 is an OSI application layer protocol; that is, it is designed to make use of the OSI presentation layer protocol. It may be used with or without the presentation protocol, and below that, it is irrelevant (to the Z39.50 protocol) what protocols are used. Most implementations of Z39.50 currently run directly over TCP/IP.

User's View:

Users (either human or electronic) run client software to connect with servers to retrieve information using the Z39.50 protocol. Many clients already exist at least in prototype version today and more are being written. Most of the major library automation vendors have announced that they will be supporting Z39.50 in either client or server mode or both. Many of the major information vendors either currently have or are working on implementations of Z39.50 for their systems. There are also a couple of Z39.50 implementations that are expected to be put in the public domain at some point. The recently announced FREEWAIS software incorporates Z39.50 Version 2 into it (the older version used a variant of the 1988 version 1 protocol). The Library of Congress acts as the maintenance agency for Z39.50 and can be contacted for a list of registered Implementors.

Z39.50 provides a protocol mechanism for accessing remote information sources. It defines the model for the interaction between two sides, a client and a server. It makes no assumptions or presumptions about how the data is actually organized in the server, nor about how the data is presented to the end user by the client.


Page 168

The model postulates one or more databases on the remote system that can be searched using attributes from defined search attribute sets, creating a result set. Records can be retrieved from the result set using agreed upon record formats.

Information types supported:

The Z39.50 protocol was designed as a general purpose search and retrieval mechanism that could be used with a wide variety of data types. The MARC format (a format used for cataloging library material among other things) and a search attribute set suitable for bibliographic and similar types of data are registered within the current version of the standard. It is assumed that, as the protocol begins to be used by other communities and for other types of data, other attribute sets and record syntaxes will be developed. This process has already begun and a generic record syntax and attribute set are already under development, as well as some others, specifically those supporting chemical structures, general science and technology, and business information. The design philosophy behind Z39.50 is that it will be used with other standards such as Postscript, SGML, ODIF (and others), to communicate a wide variety of data types, including full text, images, and many others.

The Information Services and User Support (ISUS) Working Group has been established by the RARE Technical Committee as one of the major working groups in the RARE Technical Programme. ISUS is concerned with all aspects of networked information services, group
communications and network user support. It is open to all those involved in working in these areas and should include:

Network User Support Staff: National and European Support Staff (whether RARE, RIPE, EARN, Eunet etc.) Site Computing Centre Support Staff Special subject related User Support Staff

Library Staff
Networked Information Providers
Networked Information Service Providers
Application Developers

The ISUS WG mailing list will act both as a forum for discussion amongst experts in this field and as a means for disseminating information to the wider community.


Page 171

The ISUS Working Group is chartered to have a very broad area of interest which is broken down into several sub-areas:
Network User Support
Asynchronous Group Communication
Networked Information Retrieval and Services
Liaison

Current tasks being worked on in the area of NIR include:

  • Coordination of NIR services in Europe

  • Collection of information related to NIR tools and groups. This is a joint effort with the IETF and CNI.

  • Network Interface to everything (UNITE). This group is starting to look at the user requirements for a single interface to the network (network information services, email, bulletin boards, etc.). (unite@mailbase.ac.uk)

  • Multimedia Information Services task force (MMIS). This group is a joint task force of the RARE ISUS Working Group and RARE Interactive Multimedia Working Group (mmis@mailbase.ac.uk).

USMARC/OCLC

 -----------------------------------------------------------------------

Working Group or Organisation: USMARC/OCLC

Name of group: USMARC Advisory Group; OCLC Internet Resources Cataloging Experiment

Sponsoring Organisations: OCLC, Library of Congress,
USMARC Advisory Group

Working subgroups: None

Description of main group:

OCLC and the Library of Congress have formed a working group to consider how libraries can create cataloging records for online information resources. The group initiated a cataloging experiment designed to test and verify the applicability of the cataloging rules and the USMARC format for computer files. Guidelines have been written for cataloging Internet resources and were considered by the American Library Association committee responsible for maintaining the Anglo- American Cataloging Rules. Changes to the USMARC format were initiated to accommodate a subset of these materials (electronic data resources, such as software, electronic text, bibliographic and nonbibliographic databases). USMARC format changes which were approved included an identification of type of file and a field for location and access of the resource (very much like a URL).

The group is continuing its work by looking at how online systems and services can be accommodated in USMARC. This work will be done within the USMARC Advisory Group of the American Library Association, which considers changes to the USMARC formats. Data elements will be defined with mapping to MARC fields; in some cases new fields will be proposed. This will be accomplished in conjunction with efforts by other working groups (e.g., Government Information Locator Service, or GILS).

A proposal was presented and approved in February 1994 to the USMARC Advisory Group to add data elements to the Electronic Location and Access Field (USMARC field 856). Included among these was a subfield for URL (Uniform Resource Locator). It is intended to be used instead of or in addition to other data identifying location of and access to


Page 175

a networked information resource.

Membership is closed at this point.

8. Security Considerations

Security issues are not discussed in this memo.

9. Acknowledgements

The report was very much a collaborative effort of the members of the NIR WG and in particular Peter Deutsch (who contributed the mailing list section and the basis for Section 5), April Marine, Rick Rodgers, Lars-Gunnar Olsson, Farhad Anklesaria, Marsha Perrott, Kevin Gamiel, George Brett, Barbara Thomas and all those who helped review the document. Special thanks are due to all those contributors who took the time to submit and update descriptions of their NIR tools and groups; their names are included in the templates in Sections 6 and 7.

Before final submission of the report as an RFC, independent reviewers from around the world took two or three templates each and checked them out for accuracy and currency as best they could. They liaised with the original template authors over the changes they made. The volunteers were: Larry Masinter, Marilyn Martin, Sinha Velu, Ton Verschuren, Shirley Browne, Alfred Vella, Bert Stals, Yannis Corovesis, Gerard Egan, Robert Janz and Andy Linton. They provided some very valuable input.

NIR Tool Name: Hyper-G

Brief Description of Tool:

Hyper-G is the name of an ambitious hypermedia project currently being developed as a joint effort by a number of institutes of the IIG (Institutes for Information-Processing Graz) and the Computing and Information Services Center of the Graz University of Technology and the Austrian Computer Society.

Hyper-G is designed as a general-purpose, large-scale, multi-user, distributed hypermedia information system. As such, it combines concepts of hypermedia, information retrieval systems, documentation systems with aspects of communication and collaboration, and computer supported teaching and learning. It also provides seamless integration of other systems (e.g., World-Wide Web, Gopher, WAIS) that also operate under the client/server paradigm and allows remote logins to interactive services.

In addition to hypertext links, Hyper-G allows navigation through hierarchies, queries (including full text), guided tours, and is multilingual.


Page 208

Hyper-G is currently operated at some 10 locations throughout the world, including a University Information System at the Graz Technical University. Clients and the server are available without fee for educational institutions, and are distributed as binaries for a number of platforms.

 NIR Tool Name:    SoftPages

Brief Description of Tool:

A tool to aid users in the efficient retrieval of documents, s/w, and the like from servers ( anonymous FTP, FTAM, .. ) connected to the network. In principle, it uses the X.500 Directory framework to store information about the network. This includes the network
configuration, the properties of the links that connect the network elements, location of servers and their contents. When a user looks for a particular document or s/w the above information is used to search for the object starting from the server that is
"nearest" (cheapest) to the user.

The X.500 directory services is used in several stages
get list of file-servers
get path to file servers
get attributes for computing cost of paths
search for file that is being sought

However, under present circumstances, due to lack of deployment of network information in the directory, when information is unavailable from X.500, alternate sources/methods are used. [Static-lists of file-servers, or lists of file servers from other clients (e.g., archie); Paths and/or costs are obtained from static lists or derived by other direct means (e.g., ping, traceroute); file information is sought from other servers (e.g., archie).]

User's View:

A "single window" view of the public archives connected to the network. It locates the server that contains the sought object and is near(/cheap/fast) server.

Query of files based on incomplete name is supported. The system also supports queries based on keywords.

Information Provider's View:

The information about the server contents have to be updated


Page 214

at a single place- namely, the local Directory Service Agent. The Directory Service Agent makes the information globally accessible.
It is not necessary to carry out periodic updates on one or more information servers.

  - information types supported (e.g., text, sound, etc.)

Since the system supports query on name and keywords (not on contents) all kinds of information may be supported.

WHOIS++

Date template updated or checked: 21 October, 1993

 -----------------------------------------------------------------------

NIR Tool Name: whois++ and the whois++ index service

Brief Description of Tool:

whois++ and the whois++ index service are extensions of the WHOIS protocol. They are designed to a) subsume in a standardized fashion the many enhancements which have been added to individual WHOIS servers; b) extend the flexibility of WHOIS by enriching the query syntax, and c) provide a distributed indexing system to tie the various whois++ servers into a distributed information lookup service.

The protocols describe two logically distinct types of servers that an information provider can set up. The first type is the base-level whois++ server. This contains primary information, such as entries for individual people or entries describing resources available locally. For example, if one wished to provide a campus directory through whois++, one would set up a base-level whois++ server that contained entries for each student. In addition, this base-level server must be able to generate 'forward knowledge' for the information it contains. The second type of server collects the 'forward knowledge' generated by a number of base-level servers, and can take a query sent to it and determine which of the base-level servers it indexes might contain information relevant for the query. A single physical server may contain both primary information and 'forward knowledge' for a number of other servers, and an index server can also index 'forward knowledge' for a number of other index servers, allowing a hierarchical mesh of index servers to be built. For more details on the information provider's point of view, see the 'Documentation' section of this template.

The basic information model is centered on the concept of 'templates'. A template is a collection of attribute:value pairs, where the allowable attributes are specified by the template type. The whois++ templates are based on the templates defined by the IAFA working group of the IETF. The values associated with given attributes are not necessarily limited to text, they can be digitized sound clips, etc.

Depending on the client she uses, the user will see a connection to the local whois++ base-level server. The user can ask the server for a list of templates supported by that server, and can then call up a


Page 219

blank version of the template so that she can fill in values for the attributes she knows. Once she has filled in the template as much as she wants, she issues a query to the server to find all the entries which have these attribute:value pairs. If she is not satisfied with the responses, she can then start traversing the index service to locate a server which can adequately answer her query. In addition, if a user makes frequent use of the index service, she can set 'bookmarks' which can be used later to directly contact servers she's found useful in the past, without having to traverse the index service again.
