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
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.
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.
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.
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
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
By: Name: Vincent Cate
Email address: vac@cs.cmu.edu
----------------------------------------------------------------------
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
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.
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.

ARCHIE
Date template updated or checked: 1 March, 1994
By: Name: Peter Deutsch
Email address: peterd@bunyip.com
-----------------------------------------------------------------------
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
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.

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.
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.

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
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+.

Brief Description of Tool:
HYTELNET is a terminate-and-stay-resident hypertext browser, which
gives a user full instructions for logging into telnet-accessible
sites on the Internet i.e., library catalogs, campus-wide information
systems, bulletin boards, directory services, gophers, etc. The
browser does not make remote connections. A Unix/VMS version, which
does make remote connections, has been written by Earl Fogel,
Computing Services, University of Saskatchewan. Macintosh and Amiga

NETFIND
Date template updated or checked: 1 March, 1994
By: Name: Mike Schwartz
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).

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).

PROSPERO
Date template updated or checked: 1 March, 1994
By: Name: Steven Augart
Email address: info-prospero@isi.edu
-----------------------------------------------------------------------
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.

Protocols:
What is supported:
Prospero directory service requests are formatted
according to the Prospero protocol.
Prospero does not have its own file retrieval
protocol. Files may be automatically retrieved using
FTP, NFS, AFS, and GOPHER. Loginable services may also be
accessed via TELNET.
What it runs over:
Directory service requests are layered on top of
UDP, with our own (included) reliable message delivery
layer.
Other NIR tools this interworks with:

Via anonymous FTP: PROSPERO.ISI.EDU, /pub/prospero/prospero.tar.Z
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.

Via anonymous FTP: PROSPERO.ISI.EDU, /pub/prospero/prospero.tar.Z
Via Prospero: /releases/prospero/prospero.tar.Z, in the
"#/INET/EDU/ISI/swa" 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 clients (which includes the Prospero menu browser), you should
retrieve it by version number; the name for the latest version is
prospero-alpha.5.2.tar.Z
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.

Documentation:
All of these papers are available via anonymous FTP from
PROSPERO.ISI.EDU. They may additionally be obtained through
Prospero itself by preceding the 'Full file name:' given below with
'/sites/isi.edu' and looking in the '#/INET/EDU/ISI/GUEST/prototype'
virtual system.

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 is a good third paper to read about Prospero. This one is
targeted more toward system implementors. It provides more
implementation details than the paper on organizing Internet
resources, but less of the vision of how Prospero can be used together
with other systems.

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.
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.

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 s
