JRS Semantic Web Utils

To promote the development and deployment of the Semantic Web, this site lists services available on the Web that help to build SW applications.

Note: W3C's ESWiki provides for a SW tools list; a comprehensive list of SW tools is maintained by Michael K. Bergman.

• Basic Util Set (XHTML, XML, XSLT)
• RDF Util Set (converter, generator)
• RDFa Util Set (extractor, generator)
• Query Util Set (SPARQL)
• Ontology & Reasoning Util Set (converter, validator, reasoner)
• Multimedia Metadata Util Set
