rfc1580.txt

著名的RFC文档,其中有一些文档是已经翻译成中文的的.

   Print
      prints the current document, without the numbered document
      references.  The default print command is lpr, but it may be
      defined in your local working environment by the variable
      WWW_PRINT_COMMAND.

   To access WWW with the line mode browser, type: www. The default
   first document will appear on your screen. From this point, you
   should be able to navigate through the WWW universe by reading the
   text and following the instructions at the bottom of the screen. If
   you want to start with a first document other than the default, or if
   you want to change some other aspect of the usual interaction, there
   are a number of command line parameters and options available. The
   full format of the www command to invoke the line mode browser is:

   +---------------------------------------------------------------+
   |                                                               |
   |   www      <options>  <docaddress <keyword>>                  |
   |                                                               |
   +---------------------------------------------------------------+

   where:

   docaddress
      is the hypertext address of the document at which you want to
      start browsing.

   keyword
      queries the index specified by docaddress with the supplied
      keyword(s).  A list of matching entries is displayed. Multiple
      keywords are separated by blanks.

   Options are:

   -n
      non-interactive mode. The document is formatted and displayed to
      the screen. Pages are delimited with form feed characters (FF).

   -listrefs
      adds a list of the addresses of all documents references to the
      end.  Non-interactive mode only.

   -pn
      sets the page length to n lines. Without a number, makes the page
      length infinite. Default is 24.

RFC 1580            Guide to Network Resource Tools           March 1994


   -wn
      sets the page width to n columns. The default is 78, 79 or 80
      depending on the system.

   -na
      hides references in the text. Useful, when printing out the
      document.

   -version
      displays the version number of the software.

   The commands listed above should be available in all clients. They
   may be abbreviated (CAPITAL letters indicate acceptable
   abbreviation). Case is not significant. Special characteristics of
   the line mode browser interface are:

   number
      type in a number given in [] and hit the RETURN key to follow the
      link associated to the reference.

   RETURN
      hit the RETURN key to display the next page of the current
      document (without a reference number).

4. WAIS

4.1. What is WAIS

   WAIS, Wide Area Information Server,  is a distributed information
   retrieval system. It helps users search databases over networks using
   an easy-to-use interface. The databases (called sources) are mostly
   collections of text-based documents, but they may also contain sound,
   pictures or video as well. Databases on topics ranging from
   Agriculture to Social Science can be searched with WAIS.

   The databases may be organized in different ways, using various
   database systems, but the user isn't required to learn the query
   languages of the different databases. WAIS uses natural language
   queries to find relevant documents. The result of the query is a set
   of documents which contain the words of the query: no semantic
   information is extracted from the query.




EARN Staff                                                     [Page 22]

RFC 1580            Guide to Network Resource Tools           March 1994


4.2. Who can use WAIS

   WAIS uses the client-server model to provide access to databases. You
   must be on the international TCP/IP network (the Internet) in order
   to use a client on your computer to access WAIS.

   If you have e-mail access only, or if you are not on the Internet you
   can still exploit some of the potential of WAIS. An e-mail interface
   is available at the address: [e-mail] which gives
   e-mail access to WAIS databases (see E-mail access section under
   Using WAIS below).

4.3. How to get to WAIS

   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.
