Please cite a source. The 1st web server in the world was a gateway to the CERN phone book, served dynamically. c.f.

The distinction between 'static' and 'dynamic' web pages is not in any of the HTTP, HTML, or URL specifications at all. By definition, all web resources are opaque objects that respond to a GET method. " -- editorial of the Mar/Apr 1997 issue of Web Apps Magazine, ISSN #1090-2287. Dan Connolly http://www.w3.org/People/Connolly/9703-web-apps-essay.html and more recently: =========== excerpt from Web Architecture: Describing and Exchanging Data W3C Note 7 June 1999 This version: http://www.w3.org/1999/06/07-WebData Authors: Tim Berners-Lee <timbl>, W3C Dan Connolly <connolly>, W3C Ralph R. Swick <swick>, W3C The architecture of the World Wide Web provides users with a simple hypertext interface to a variety of remote resources, from static documents purely for human consumption to interactive data services. HTML, the data format that facilitated the widespread deployment of the Web, started by adding URI based linking to word processor style rich text to provide basic global hypertext functionality. The addition of forms to HTML provided a minimal but functional user interface to interactive data services. While this HTML infrastructure has facilitated a revolution in global information technology, it suffers from the inevitable limitations of a "one size fits all" solution: rich document structures are lost as the content is squeezed into the primitive structures of HTML. Similarly, the cost of squeezing rich data structures into and out of HTML is paid in efficiency and integrity. Now that the Web has reached critical mass as a medium for human communication, the next phase is to build the "Semantic Web". The Semantic Web is a Web that includes documents, or portions of documents, describing explicit relationships between things and containing semantic information intended for automated processing by our machines. =========== > One souce of > information per URL.
