---++ODS SIOC Reference
This article outlines the mapping of ODS data to the SIOC ontology for the purpose of constructing [[SPARQL]] Queries against OpenLink Data Spaces [[ODS]] Data.

*Note*: 

   * To validate a particular SIOC RDF Data Set (in plain old RDF form), you can use the [[http://www.w3.org/RDF/Validator/][W3C RDF Validation Service]]
   * You can actually create you own Data Spaces and then experiment with these queries by opening accounts at: http://demo.openlinksw.com/ods (for very temporary and volatile usage) or http://myopenlink.net:8890/ods (for less volatile usage)
   * You can run most (if not all) of the queries with minimal modification using the following SPARQL Query Services: http://demo.openlinksw.com/sparql/ (using the 'demo' user account) and http://myopenlink.net:8890/sparql/ (assuming you have an account with this service)
   * Default Graph URI value used in the queries below is: http://demo.openlinksw.com/dataspace

#DiscussionDataspace
---+++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.

#GenericDataspaceConstructQueries

---+++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).
