    RDF View for ODS Discussions

    IMPORTANT! 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 ODS RDF Views Deployment and Demo Scripts.
    sparql prefix ods: <http://www.openlinksw.com/virtuoso/ods/>

    		( in forum_name varchar not null)
    		option (returns "http://^{URIQADefaultHost}^/dataspace/discussion/%U").
    	create iri class ods:nntp_post "http://^{URIQADefaultHost}^/dataspace/discussion/%U/%U"
    		( in group_name varchar not null, in message_id varchar not null)
