Software modeling techniques and the semantic Web

Following the success of XML, W3C envisions the semantic Web (Berners-Lee et al., 2001) as the next generation of Web in which data are given well-defined and machine-understandable semantics so that they can be processed by intelligent software agents. Semantic Web can be regarded as an emerging area from the knowledge representation and the Web communities. The software engineering community can also play an important role in the semantic Web development. Modeling and verification techniques can be useful at many stages during the design, maintenance and deployment of semantic Web ontology. We believe semantic Web will be a new research and application domain for software modeling techniques and tools. For example, recent research results have shown that UML, Z (Woodcock and Davis, 1996) and Alloy (Jackson, 2002) can provide modeling, reasoning and consistency checking services for semantic Web.
