There are many WAIS servers throughout the network. A
directory-of-servers database is available at several sites. You can
address a query to it, e.g., to find out what databases are available
on a particular subject. This database is also available via
anonymous FTP from Think.com in the directory /wais as file
wais-sources.tar.Z.
If you do not have access to a WAIS client, (at least) two
demonstration sites are available to allow you to get acquainted with
WAIS. You can telnet to:
+---------------------------------------------------------------+
| |
| quake.think.com (login: wais) |
| sunsite.unc.edu (login: swais) |
| |
+---------------------------------------------------------------+
The two demonstration sites above run swais (Screen WAIS), a simple
WAIS client for Unix.
4.4. Using WAIS
There are many freely available client software programs for various
operating systems (Unix, VMS, MVS, MS-DOS, OS/2 and Macintosh) and
for specific environments (GNU Emacs, X-Windows, Openlook, Sunview,
NeXT, and MS-Windows). See the list of freely available client
software in Appendix A.
The client interface differs slightly on different platforms.
However, the queries are performed in the same way, whatever the
interface.

RFC 1580 Guide to Network Resource Tools March 1994
* Step 1: The user selects a set of databases to be searched from
among the available databases.
* Step 2: The user formulates a query by giving keywords to be
searched for.
* Step 3: When the query is run, WAIS asks for information from each
selected database.
* Step 4: Headlines of documents satisfying the query are displayed.
The selected documents contain the requested words and phrases.
Selected documents are ranked according to the number of matches.
* Step 5: To retrieve a document, the user simply selects it from the
resulting list.
* Step 6: If the response is incomplete, the user can state the
question differently or feed back to the system any one or more of
the selected documents he finds relevant.
* Step 7: When the search is run again, the results will be updated
to include documents which are similar to the ones selected,
meaning documents which share a large number of common words.
4.4.1. E-mail access:
You can query WAIS databases and retrieve documents by sending
commands in the body part of an e-mail message to
waismail@quake.think.com. The Subject: line is ignored. The important
commands are (a vertical bar (|) indicates a choice of parameters):
help
to get the help file
maxres number
to set the maximum number of results to be returned.
search source-name | "source-name1 source-name2 ..." keywords
where:
source-name
is a source name as found in the directory-of-servers (with or
without the .src ending). Use double-quotes (") to group
several sources to be searched.
keywords
are the words you would normally type into a query.
EARN Staff [Page 24]
RFC 1580 Guide to Network Resource Tools March 1994
You may specify several search requests in a mail message. If you
don't know what sources you can search, just try anything. If the
source name is not recognised, you'll get a list of sources.
retrieve docid
to retrieve a document from a database. docid is a DocID as
returned by a search above. You may put more than one retrieval
request in a mail message, but you must leave a blank line between
requests. The docid must be written exactly as returned by a
search request, including any spaces. You can retrieve non-text
documents as well as text. If the document is of type TEXT or WSRC
you will get the result directly. Other types will be UUENCODED.
DocID: docid
same as retrieve. This form is identical to the form which is
returned by a search request. It makes it easy to use the reply
mail function to retrieve results.
4.5. Examples
When you log in to the demonstration site at quake.think.com, you
have immediate access to the directory-of-servers database via the
swais client software. To find recipes using papaya, you would select
the recipes database and give papaya as the keyword. Here are the
results of the search:

4.6. Learning more about WAIS
A bibliography of documents, services and sources for WAIS is
maintained by Barbara Lincoln Brooks of WAIS Inc. The bibliography is
available from ftp.wais.com in the directory /pub/wais-inc-doc along
with many other WAIS documents.
There are currently four main FTP sites for WAIS documentation and
software:

RFC 1580 Guide to Network Resource Tools March 1994
* ftp.cnidr.org
* ftp.wais.com
* quake.think.com
* sunsite.unc.edu
For information on free WAIS software contact freewais@cnidr.org
Mailing list: wais-discussion@wais.com

WAIS was developed at Thinking Machines Corporation.
5. ARCHIE
5.1. What is ARCHIE
Archie is an information system. It offers an electronic directory
service for locating information in the international TCP/IP network
(the Internet).
The best known use of archie is for scanning a database of the
contents of more than 1000 anonymous FTP sites around the world.
Currently, this database contains more than 2,100,000 file names from
anonymous FTP sites. This database is known as the archie database.
The files made available at anonymous FTP sites are software packages
for various systems (Windows, MS-DOS, Macintosh, Unix, etc.),
utilities, information or documentation files, mailing list or Usenet
group discussion archives. At most FTP sites, the resources are
organized hierarchically in directories and subdirectories. The
database tracks both the directory path and the file names.
The archie database is automatically updated, thereby ensuring that
the information is accurate. Using this database, users can easily
find the the location of files they need without logging onto several
machines.
5.2. Who can use ARCHIE
Users on any network can access the archie database by electronic
mail. Other means of access are available to users on the Internet
(see the section Using ARCHIE below for details).
You are requested to respect a few basic rules when you request
information from an archie server:
EARN Staff [Page 27]
RFC 1580 Guide to Network Resource Tools March 1994
* avoid connecting during working hours; most of the archie
servers are
not dedicated machines, they have local functions as well.
* make your queries as specific as possible; the response will be
quicker and shorter.
* user interfaces installed on your computer contribute to reduce
the
load on the server sites, please use them.
* use the archie server closest to you and, in particularly, don't
overload the transatlantic lines.
5.3. How to get to ARCHIE
