A few weeks ago there was the short-Protege course in Vienna. We were invited to give a talk on ontopPro and now I want to share the material.
It's tutorial on how to create mappings using ontop, how inference (OWL 2 QL and RDFS) plays a role answering SPARQL queries in ontop, and how ontop's support for on-the-fly SQL query translation enables scenarios of semantic data access and data integration.
The material includes all the worked out mappings, SPARQL queries and SQL databases and it's full with useful hints on how to use OBDA for different purposes.
Please take a look and send me any feedback you may have :)
