Hi Aldo,
Yes, I have seen this issue myself before and reported to development
as I am not convinced the RDFView graphs should be listed or treated
the same as the other graphs IRIs for triples stored in the database.
The way I have deleted/dropped then is using the "drop quad map
<storage-name>" as detailed in the following whitepaper on mapping
relational data to RDF with Virtuoso's RDFViews:
http://virtuoso.openlinksw.com/Whitepapers/html/rdf_views/
virtuoso_rdf_views_example.html
You will note that the RDF Schema Object UI silent runs this command
before creating a new quad map for new RDFVIews. I do believe having
an unpublish command as you suggest either in the graph UI or
probably better in the RDF Schema Object UI would be a good thing.
Best Regards
Hugh Williams

Hi,
I am having trouble removing a graph that was created as a result of
executing an RDF View definition ( I remember the publish part of the
RDF View process failed, but can't remember exactly why. This is when
we were pushing the envelope a bit ).
I can see this test graph listed under Conductor > RDF > Graphs and I
can also see that it contains data ( via SPARQL ). However, clicking
"Delete" does not remove it.
This is not a blocker, but I would love to know what's going on.
Some questions that come to my head:
* How are these "virtual" graphs stored?
* What can I do to gather more info so we can diagnose this? what info
would that be?
* In the context of "virtual graphs" ( = RDF Views over VDB ) what
exactly does Delete mean? Does it mean: delete the RDFView metadata?
** In this case, why not change the name to "unpublish" so it doesn't
get confused with: Delete (all the data in the graph)
Thanks!
