I am relatively new to Stardog and am trying to work with the Virtual graph concepts.
So, tried to create a Virtual graph using MySQL as the source. The virtual graph is created successfully and by querying it, I could fetch proper data.
Further, I have exported the data into a named graph and then tried to return an RDF graph running a DESCRIBE query with a filter but unfortunately, I am not getting any results-
I have also tried running a CONSTRUCT query with a filter, still did not receive any results-
I think am missing some crucial steps here, could you kindly help me pointing it out.
