  74. <p>In article <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#54;&#52;&#46;&#46;&#46;&#64;&#99;&#101;&#114;&#110;&#118;&#97;&#120;&#46;&#99;&#101;&#114;&#110;&#46;&#99;&#104;">&#54;&#52;&#46;&#46;&#46;&#64;&#99;&#101;&#114;&#110;&#118;&#97;&#120;&#46;&#99;&#101;&#114;&#110;&#46;&#99;&#104;</a> I promised to post a short summary of the
  75. WorldWideWeb project. Mail me with any queries.</p>
  76. <p>WorldWideWeb - Executive Summary</p>
  77. <p>The WWW project merges the techniques of information retrieval and hypertext to
  78. make an easy but powerful global information system.</p>
  79. <p>The project started with the philosophy that much academic information should
  80. be freely available to anyone. It aims to allow information sharing within
  81. internationally dispersed teams, and the dissemination of information by
  82. support groups.</p>
  83. <p>Reader view</p>
  84. <p>The WWW world consists of documents, and links. Indexes are special documents
  85. which, rather than being read, may be searched. The result of such a search is
  86. another ("virtual") document containing links to the documents found. A simple
  87. protocol ("HTTP") is used to allow a browser program to request a keyword
  88. search by a remote information server.</p>
  89. <p>The web contains documents in many formats. Those documents which are
  90. hypertext, (real or virtual) contain links to other documents, or places
  91. within documents. All documents, whether real, virtual or indexes, look similar
  92. to the reader and are contained within the same addressing scheme.</p>
  93. <p>To follow a link, a reader clicks with a mouse (or types in a number if he or
  94. she has no mouse). To search and index, a reader gives keywords (or other
  95. search criteria). These are the only operations necessary to access the entire
  96. world of data.</p>
  97. <p>Information provider view</p>
  98. <p>The WWW browsers can access many existing data systems via existing protocols
  99. (FTP, NNTP) or via HTTP and a gateway. In this way, the critical mass of data
  100. is quickly exceeded, and the increasing use of the system by readers and
  101. information suppliers encourage each other.</p>
  102. <p>Making a web is as simple as writing a few SGML files which point to your
  103. existing data. Making it public involves running the FTP or HTTP daemon, and
  104. making at least one link into your web from another. In fact, any file
  105. available by anonymous FTP can be immediately linked into a web. The very small
  106. start-up effort is designed to allow small contributions. At the other end of
  107. the scale, large information providers may provide an HTTP server with full
  108. text or keyword indexing.</p>
  109. <p>The WWW model gets over the frustrating incompatibilities of data format
  110. between suppliers and reader by allowing negotiation of format between a smart
  111. browser and a smart server. This should provide a basis for extension into
  112. multimedia, and allow those who share application standards to make full use of
  113. them across the web.</p>
  114. <p>This summary does not describe the many exciting possibilities opened up by the
  115. WWW project, such as efficient document caching. the reduction of redundant
  116. out-of-date copies, and the use of knowledge daemons. There is more
  117. information in the online project documentation, including some background on
  118. hypertext and many technical notes.</p>
  119. <p>Try it</p>
  120. <p>A prototype (very alpha test) simple line mode browser is currently available
  121. in source form from node info.cern.ch [currently 128.141.201.74] as</p>
  122. <p>/pub/WWW/WWWLineMode_0.9.tar.Z.</p>
  123. <p>Also available is a hypertext editor for the NeXT using the NeXTStep graphical
  124. user interface, and a skeleton server daemon.</p>
  125. <p>Documentation is readable using www (Plain text of the instalation instructions
  126. is included in the tar file!). Document</p>
  127. <p>http://info.cern.ch/hypertext/WWW/TheProject.html</p>
  128. <p>is as good a place to start as any. Note these coordinates may change with
  129. later releases.</p>
