Instance of Individuals from database

[Wellington Camargo <wc...@feb.unesp.br>]

Hi all.

    Firstly, excuse my limited English, I'm a student yet.

    I have a Moodle database with data about students, and have an OWL
    file with the ontology. I have too a rule file with the rules which
    allow the inference about the student's performance.

    The OWL is only a model, I would like to get the database
    information, use it as individuals and apply the inference rules to
    get the performance.

    What is the best way to do it?


Thank you,
Wellington.

Essentially what you are asking for is mapping relational data to RDF. 
As it happens, there is a current W3C activity to standardise the basic 
approach in this area. See [1] for details. D2RQ [2] is one of the more 
mature implementations of R2RML, which works well with Jena
