Re: [Rdfapi-php-interest] Questions about OntModel

[<jsp...@gm...>]

Hi,

I am not sure how exactly the OntModel works but be aware! FOAF and
relationship module are not ontologies but "plain" RDF Schemas. While
I was playing with Java tool Jastor for generating model from
ontologies I was faced with this problem and got into trouble.
