The World Wide Web Consortium announced the publication of “Architecture of the World Wide Web”. The authors of this document, W3C’s Technical Architecture Group (TAG), invite review by the community of this description of principles that guide the evolution of the Web. The TAG invites comments on the First Edition by 5 March 2004. The Web architecture consists of three fundamental concepts: identification (URIs), interaction (protocols such as HTTP and SOAP), and representation (formats such as HTML, SVG, and PNG). These three branches are typified by the familiar user experience of using a browser to click on a link that identifies a Web site, leading to interaction with the Web site (referred to generically as a “Web resource”), and then to the display of information in the browser. Some of the topics covered by the Architecture Document include important considerations when managing a Web server, such as persistence; how to take advantage of “safe” Web interactions and allow bookmarking and caching; and pitfalls to avoid when using content negotiation. The document also explains how XML fits into the Web, and how to ensure that new formats “play well” on the Web. www.w3.org
