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 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)
