Legend description

The W3C technical architecture diagram depicts a two-layer model: the World Wide Web architecture (labeled "One Web") is built on the Internet (Interner) architecture. The rich Web layer in the figure shows the areas of concern and developing technologies of W3C.

Web architecture is depicted as a series of layers, each layer built on top of the other. From bottom to top:

• URI/IRI, HTTP
• Web Architectural Principles
• XML Infosets; RDF(S) Graphs
• XML, Namespaces, Schemas, XQuery/XPath, XSLT, DOM, XML Base, XPointer, RDF/XML, SPARQL

The top level contains six boxes, corresponding to the main W3C activity groups: Web Applications, Mobile, Voice, Web Services, Semantic Web, and Privacy.

• The "Interaction" box lists: XHTML, SVG, CDF, SMIL, XForms, CSS, and WCID.
• The "Mobile" box lists XHTML Basic, Mobile SVG, SMIL Mobile, XForms Basic, CSS Mobile, MWI BP.
• The "Voice" box lists VoiceXML, SRGS, SSML, CCXML, and EMMA
• The "Web Services" box lists SOAP, XOP, WSDL, WS-CDL, and WS-A.
• The "Semantic Web" box lists OWL, SKOS, and RIF.
• The "Privacy" box lists P3P, APPEL, XML Encryption, XML Signature, and XKMS

An orange bar connects these areas: Web Accessibility, Internationalization, Mobile Access, Device Independence, and Quality Assurance ).

This example diagram shows the basic framework of the World Wide Web and the focus of W3C's work.

The foundation of URI, HTTP, XML and RDF supports five aspects of work. Topics such as web accessibility, internationalization, device independence, and quality management are integrated into W3C technologies.

The W3C is working to transform the World Wide Web from its original design (basic HTML, URIs, and HTTP) into the model it will need in the future. W3C's technology will help the future World Wide Web become a highly stable, scalable and adaptable basic framework in the information world.
