Hello,
I have a doubt about how to use custom mapping within D2R Server. I used to use
TopBraid Composer as a D2RQ GUI. There, you have an ontology file and a mapping
file which storages the relationships between the ontology and the database.
Before Topbraid, I was coding with D2RQ library.
Now, I am developing a D2R Server but I don't find any way of mapping between
an existing ontology and a database. If I am right, the ontology is created by
the server from the database, and this mapping can be customized (please
correct me if I am wrong and I can reuse an existing ontology).
My idea is to reproduce my ontology in the mapping D2R Server file. My ontology
is not very complex so I think this is feasible. Nevertheless, I don't know how
to do simple things like creating a class hierarchy.
Having a simple class hierarchy like:
- Person--- Student--- Teacher
Being Student and Teacher subclasses of Person, how can I get this in D2R
Server if I only have Student and Teacher tables in the database (Person is new
class I would like to create in the ontology)?
I've tried to use "d2rq:additionalClassDefinitionProperty" with
"rdfs:subClassOf", but I have no luck.
Thank you,jfcg
