Holger, I can do that but help me out here - what I'd like most is to be able to work just in Topbraid setting-up ontologies, adding instances (perhaps saved in an AG store) and querying it in SPARQL (possibly run inside Sparql-motion scripts) including spatial queries (just the basics - distance-between, objects within x-kms of point etc.)
What's your best assessment of when that scenario will be possible? (I'll keep quiet about it after this!)
