Q: Filling up RDF data from a relational database I am creating an ontology based on a relational database. Some classes in my ontology are correspondent to some tables in the relational database (PostgreSQL).
I already read some documents about mappings from the W3C website. Especially this one which looks to me the right approach I should follow.
This generated a couple of questions:


*

*I suspect that this mapping approach will offer me just a RDF view of the database. Am I right?

*Once I have finished this mapping, where should I execute it? I saw some mapping processors in the reference section on the documentation but all of it looks to be outdated, some with more than 5 years of inactivity.


What I really need is a way to extract data values from some tables putting in my ontology. 

A: The solutions found were:


*

*No, I wasn't right. They also allow filling it up the data.

*I have decided to use Ontop plugin inside protegé, even if I am not sure about the kind of mappings they use.
