Reification Support

TopBraid 9 introduces support for RDF 1.2 reification in addition to TopBraid’s own reification approach that was based on “long URIs” and dash:reifiableBy. At the time of writing, RDF 1.2 is not yet officially published and RDF 1.2 support in TopBraid is marked experimental. However, it should be fully functional, and has the advantage of being natively supported by SPARQL 1.2 and Turtle 1.2. There is a Modify action available in the Home assets of each collection to convert native reified triples to RDF 1.2. TopBraid will drop its native reification support once the RDF 1.2 syntax is sufficiently stable.
