I want to use stardog domain ontology as source dataset by giving the url of domain ontology in the dprod endpoint url and dprod: protocol as stardog. Could someone help me in figuring out the endpoint url format to used in dprod to connect to stardog and also what should be the dprod:protocol. Currently I have used “localhost:port/dbname/query”^^schema:URL in the endpoint url and “stardog” in the protocol.
