Produce RDF - for JSON-LD 1.1, find a tool to convert it to any other RDF syntax. The JSON-LD playground will do that. If it can do file to file, any implementation language will do. Exec a process to do the conversion. Or http://rdf.greggkellogg.net/distiller which offers conversion as a service. ---- There is a JIRA waiting for a contribution: https://issues.apache.org/jira/browse/JENA-1948 Andy > > -----Ursprüngliche Nachricht----- > Von: Andy Seaborne <[email protected]> > Gesendet: Sonntag, 25.
