[Semediawiki-user] Connection rejected for SMW SPARQLstore and Virtuoso

[Laurent A. <lal...@gm...>]

I am slowly coming from under the rock I have been for the past two years
at work and rebuilding my SMW instance on a new infrastructure. As part of
that rebuild, I am trying to use Virtuoso as a triple store.

Virtuoso itself seems to be working.
I was able to load a full RDF export the wiki as a test and run queries
against it.

SMW is working as well and I can rebuild properties on the new instance.

My current problem is when I try connecting the two.

SMW_refreshData is giving me an error 500 "Query rejected" on the very
first page.

I read previous discussions about this and granted the recommended roles to
the SPARQL account in Virtuoso.

I also tried running the query issued by SMW directly from Virtuoso but
this is giving me a different error (something like... syntax error after <
on line 15).

Does this look familiar to anyone?

My current assumption is that I have an incomplete configuration on the
Virtuoso side and that SMW cannot even connect to the triple store to run
its query. That could explain why the error message is different from
running the query manually.
