[Crm-sig] problem of formulating queries is SPARQL it has transferred the old relational paradigm onto the graph structure?

Martin,

sure, I can see the provocation and obviously fell for it. But you
should keep in mind that Linked Data and SPARQL could be or already
are major drivers for CIDOC CRM vocabulary adoption in cultural
heritage institutions and generally data sets.

I hope this thread will help to foster a good conversation around LD
and CIDOC CRM. I plan to address the issue again in July.
