Hi all,
I'm trying Virtuoso and its RDF graph groups for the first time. I'm using
Virtuoso 7.2 Open Source edition.
I have a group setup with two members (I see them in the database tables).
When I do a sparql select, it appears that the group is not being expanded
to the members as described in the documentation. Below is the query with
what I see with "Explain" in the interactive sql editor. I'm sure I'm
missing something very obvious. What am I missing? Is this feature
available in the open source edition?
Thanks,
Shahim
sparql
