W3C Releases Web Services Schemes
The Cambridge, Mass.-based standards organization released a first draft of its Web Service Architecture Usage Scenarios. The draft document defines a collection of usage scenarios and use cases that both illustrate the use of Web services and are used to generate requirements for the Web services architecture, as well as to evaluate existing technologies, the W3C said.
The document, produced by the W3Cs Web Services Architecture Working Group, includes a series of use cases for Web services. The use cases include a travel agent case scenario and an "EDI-like purchasing" Web services scenario, according to W3C officials.
The W3C also this week released the second edition of XHTML 1.0, the Extensible Hypertext Markup Language, as a W3C Recommendation. XHTML 1.0 is a reformulation of HTML in XML, the W3C said. XHTML adds "the rigor" of XML to Web pages, the organization said.
However, while issued as a new release, the second edition is not exactly a new version, the W3C said. It brings the XHTML 1.0 recommendation up to date with input from such areas as the XML and HTML communities and ongoing work within the W3Cs HTML Working Group.
Also, the W3Cs Web Ontology Working Group this week released three first working drafts. The working group released the feature synopsis, abstract syntax and language reference drafts, which describe the Ontology Web Language (OWL) 1.0 and its subset OWL Lite.
W3C officials said automated tools use common sets of terms known as ontologies to power services such as more accurate Web search, intelligent software agents and knowledge management. OWL is used to publish and share ontologies on the Web.
