---+++RDF View for ODS Discussions

<strong>IMPORTANT!</strong> The following code is part of the ODS global VIEW regarding the Discussions part, it is not a separate VIEW and is strongly recommended NOT to be executed directly. Instead, you should use the code from [[VirtRDFViewODSGlobal][ODS RDF Views Deployment and Demo Scripts]].
