Re: The crazy 'qualified' idea:-)

Thanks Ivan…

Just to show the “simple” model of allowing a Constraint to have another subordinate Constraint:

    odrl:constraint [
      a odrl:Constraint ;
      odrl:operator odrl:eq ;
      odrl:event <http://epl.com/vocab/afterMatch> ;
      odrl:constraint <http://example.com/30minEmbargo <http://example.com/30minEmbargo>>;
    ].

<http://example.com/30minEmbargo <http://example.com/30minEmbargo>>
    a odrl:Constraint ;
      odrl:operator odrl:eq ;
      odrl:dateTime “P30M”^^xsd:duration .

The semantics would be that the subordinate constraint would further constrain the “parent” constraint.
