    Discussion / Conversation Data Space

    Each Wiki, Weblog, Feed Manager, Bookmark Manager, Mail, and Photo Gallery, application instance with "Conversation" functionality enabled results in the generation of SIOC instance data from the ODS Discussion Application. For example, in the Weblog Data Space this implies that all comments are delegated to the Discussion Data Space application (which is an application of Virtuoso's NNTP engine) and exposed as SIOC data automatically.

    Using SPARQL CONSTRUCT to Export SIOC based RDF Data Sets

    CONSTRUCT based SPARQL queries are very useful when trying to expose RDF (via a SPARQL Endpoint) to RDF Data Set consumers that do not support SPARQL. In a sense, the SPARQL CONSTRUCT statements as part of a SPARQL Protocol payload deliver a Data Web (Web 3.0) Experience to Interactive-Web Clients (Web 1.0).
