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.

World-Wide Web

Date template updated or checked: 28th January, 1994

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.

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.

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
text version of the installation instructions is included in the tar
file!

Printable (postscript) documentation and articles are in /pub/www/doc
on info.cern.ch.

X.500 White Pages

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

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.
