Great :)

It's really healthy to see working prototypes being shared here.

I made a small start in this direction too, though nothing using W3C
format yet. I took the Ravensberg RDF data (POIs plus 'good relations'
ecommerce markup) and loaded it into an RDF SPARQL database:

Sample query below. It shows that the business-related POIs have
categories. It's a generic RDF store, has no notion of geo-sparql yet,
... but if anyone wants the data to play around with, the above links
should help - or just ask.
