[Rdfapi-php-interest] Questions about OntModel

[Alexandre P. <al...@pa...>]

Hi,

I used RAP to write a FOAF parser [1], in which I use MemModel to read
my RDF files.

I recently thaught about FOAF extensions, as the Relationship
vocabulary [2], which defines some subproperties of foaf:knows.

At the moment, with my MemModel, I use
findFirstMatchingStatement($subject, FOAF::KNOWS, $null) to get all
foaf:knows classes related to my subject.

But, I assume, it won't work if the RDF files that use rel:worksWith
instead of foaf:knows.

Is that the role of OntModel to make this kind of queries work ? If
so, should I have to write somewhere (in vocabulary folder) the
Relationship model and its mapping with FOAF ?

Thanx for any advice on this point.
