Re: Populate an owl ontology with mysql database
Thank you! It seems to do want I want. To explain what I'm doing : I've first create an ontology (owl file with Protege 4) and now I am developing a web portal referring to this ontology ( but not directly linked to it ). Now I want to display in this web portal the ontology populated with the individuals that are stored in the portal db. My Goal is to visualize in a web page of the portal, the ontology and his individuals (populated dynamically from the portal db) using semantic queries. It's a java portal on a Tomcat server, maybe D2RQ could help me to define mappings and populate my owl ontology.

Re: Populate an owl ontology with mysql database
David, I would suggest using something like D2RQ to dump your data as RDF. You may be able to get the mapping you want from this but if not, load it into TDB and run some SPARQL transforms (constructs) to get it how you want it.

Re: Populate an owl ontology with mysql database
Hello David Not sure how your data is arranged on MySQL, but have a look on D2R ( http://d2rq.org/), which maps relational data to RDF. cheers -- diogo patrão On Sun, May 19, 2013 at 7:57 AM, David De La Peña wrote: > Hello, > could I use Jena to populate individuals form a mysql db to an owl > ontology? > > Thank you, > > -- > David DE LA PEÑA >
Re: Populate an owl ontology with mysql database
Hello, could I use Jena to populate individuals form a mysql db to an owl ontology? Thank you, -- David DE LA PEÑA
