It aims to allow information sharing within<br \/>\ninternationally dispersed teams, and the dissemination of information by<br \/>\nsupport groups.<br \/>\nReader view<br \/>\nThe WWW world consists of documents, and links.\u00a0 Indexes are special documents<br \/>\nwhich, rather than being read, may be searched. The result of such a search is<br \/>\nanother (\u201dvirtual\u201d) document containing links to the documents found.\u00a0 A simple<br \/>\nprotocol (\u201dHTTP\u201d) is used to allow a browser program to request a keyword<br \/>\nsearch by a remote information server.<br \/>\nThe web contains documents in many formats. Those documents which are<br \/>\nhypertext,\u00a0 (real or virtual) contain links to other documents, or places<br \/>\nwithin documents. All documents, whether real, virtual or indexes, look similar<br \/>\nto the reader and are contained within the same addressing scheme.<br \/>\nTo follow a link,\u00a0 a reader clicks with a mouse (or types in a number if he or<br \/>\nshe has no mouse). To search and index, a reader gives keywords (or other<br \/>\nsearch criteria). These are the only operations\u00a0 necessary to access the entire<br \/>\nworld of data.<br \/>\nInformation provider view<br \/>\nThe WWW browsers can access many existing data systems via existing protocols<br \/>\n(FTP, NNTP) or via HTTP and a gateway. In this way, the critical mass of data<br \/>\nis quickly exceeded, and the increasing use of the system by readers and<br \/>\ninformation suppliers encourage each other.<br \/>\nMaking a web is as simple as writing a few SGML files which point to your<br \/>\nexisting data. Making it public involves running the FTP or HTTP daemon, and<br \/>\nmaking at least one link into your web from another. In fact,\u00a0 any file<br \/>\navailable by anonymous FTP can be immediately linked into a web. The very small<br \/>\nstart-up effort is designed to allow small contributions.\u00a0 At the other end of<br \/>\nthe scale, large information providers may provide an HTTP server with full<br \/>\ntext or keyword indexing.<br \/>\nThe WWW model gets over the frustrating incompatibilities of data format<br \/>\nbetween suppliers and reader by allowing negotiation of format between a smart<br \/>\nbrowser and a smart server. This should provide a basis for extension into<br \/>\nmultimedia, and allow those who share application standards to make full use of<br \/>\nthem across the web.<br \/>\nThis summary does not describe the many exciting possibilities opened up by the<br \/>\nWWW project, such as efficient document caching. the reduction of redundant<br \/>\nout-of-date copies, and the use of knowledge daemons.\u00a0 There is more<br \/>\ninformation in the online project documentation, including some background on<br \/>\nhypertext and many technical notes.<br \/>\nTry it<br \/>\nA prototype (very alpha test) simple line mode browser is currently available<br \/>\nin source form from node\u00a0 info.cern.ch [currently 128.141.201.74] as<br \/>\n\/pub\/WWW\/WWWLineMode_0.9.tar.Z.<br \/>\nAlso available is a hypertext editor for the NeXT using the NeXTStep graphical<br \/>\nuser interface, and a skeleton server daemon.<br \/>\nDocumentation is readable using www (Plain text of the instalation instructions<br \/>\nis included in the tar file!). Document<br \/>\nhttp:\/\/info.cern.ch\/hypertext\/WWW\/TheProject.html<br \/>\nis as good a place to start as any.
