]> RDF Service Discovery Descriptions This vocabulary defines terms used to describe RDF services so that they can be discovered. A RDF service is characterised by the vocabularies, classes, properties, and concepts it can handle. The description is built as a set of properties of the connection point resource (a node which URI is the URL of the service). Services can publish their SDDs as sets of 'keywords', so they can be discovered via keyword-based lookups. In absense of RDF-aware search engines, regular search engines can be used (see RDFGoo <http://labs.intellidimension.com/rdfgoo/> and RDF Facets <http://swdev.nokia.com/facets/RDF_Facets.pdf> for details). &vocabid; Sergei Egorov <esl@ariadnegenomics.com> Copyright © 2006 Sergei Egorov OWL metadata & format Copyright © 2005 Richard Newman and Ian Davis &ddl; ddl text/html HTML application/rdf+xml OWL 2006-03-05 handles namespace URI The URI of the namespace understood by the service. The URI should include trailing # or /. The format is the same as used in N3 @prefix, RDF/XML xmlns declarations, and vann:preferredNamespaceUri annotations. 2006-03-07 handles instances of A Class of resources understood by the service. A resource belonging to this class (having it as its rdf:type) may serve as a potential input to the service. 2006-03-07 handles property A property (relation) understood by the service. An RDF statement expressed via this property may serve as a potential input to the service. 2006-03-07 handles concepts in A SKOS concept scheme understood by the service. A concept in this scheme may serve as a potential input to the service. 2006-03-07
