RDB2RDF Usecase

Hi Soeren:
On Friday, we discussed adding usecases to our recommendation.
I'm wondering if you have any good usecases from Triplify.
I looked on the website and their certainly seem to some interesting 
stories.
If you could write one up, that would be great.

All we need is a short (one or 2 paragraph) description of a problem
that was solved by mapping Relational data to RDF or OWL

All the best, Ashok
