Hi Marc

Can you please provide details on the method you are attempting to load the PubMed data into Virtuoso with ?

I presume you have setup your own Virtuoso instance for hosting this, in which case can you provide:

1. The version is use, type virtuoso-t -? to determine this
2. A copy of your virtuoso.log file

You might also what to run the Virtuoso RDF_AUDIT_METADATA which is a function to audit and fix metadata corruption in the RDF Quad Store:

Hello,

I'm receiving an error while trying to load an N3 version of PubMed.

Error SR175: Uniqueness violation : Violating unique index
RDF_QUAD_POGS on table DB.DBA.RDF_QUAD. Transaction killed.

What does it really mean? What I think it mean is that the hash
function space isn't big enough and is returning a collision in the
index. So if this is really the problem, how can increase the space of
the index... only 9% of PubMed is currently load and I'm receiving
this.

Thanks,

Marc-Alexandre
