Re: Semweb ontology-to-ontology

Dear Paul,
I suggest you to define mappings between such schemata in order to
allow a joint access to data.
For defining the mappings you can do it manually if you don't have to
align hundreds of schemata, or you can apply automatic approaches (a
good overview is explained in the book "Ontology Matching"
(http://www.amazon.com/Ontology-Matching-J%C3%A9r%C3%B4me-Euzenat/dp/3642387209).
Once you have defined such mapping you can build SPARQL constructs as
suggested by Martynas.

Mauro.

We plan to code up data connectors to perform ETL operations and populate the repository with RDF data that adheres to this common ontology. The data sources use various access methods, data formats and schemas.

In the non-webweb world our data connectors could leverage these technologies.

We'd like to limit our data connector code to generating RDF triples from a data source, and rely on some other technology to, given some kind of ontology-to-ontology mapping rules, transform RDF data adhering to the source ontology into RDF data adhering to the repository's target ontology.
