Hi Marcus

I've been meaning to announce this on the TAG and GUID group lists and your email has just prompted me...

I'm organising a workshop on RDF, Ontologies and Meta-data at the eScience Centre in Edinburgh from the 7-9th June - immediately preceding the GUID-2 workshop. The workshop will begin with a morning devoted to a tutorial session from Oracle on RDF and their triple store. The afternoon follows this with presentations from researchers on building triple stores and then a discussion session on the scalability of RDF - which I believe is still a problem. So with any luck your questions might get answered there.

Details of the workshop are being firmed up on the wiki at:

Registration for the even is open at:

The aim of the workshop is to try and understand exactly where we are with these technologies, what are the main issues facing us, what is achievable in the near future and what are real problems that need longer term research to answer.

I'm sure many of you would find the workshop interesting and could contribute to the discussion sessions, so feel free to sign up and come along.
