Do you at least agree that we must provide RDF file that are valid against
our Ontology ? Because this is our goal.

Right. And each have an editor.

This piece of code only allows to validate the RDF files with Protégé
(Just like you would add a DTD or a Shema link to validate an XML file).

When all the files are provided. We decided that we would assign
reviwer(s) to make sure the files do validate. Meanwhile it is up to the
editors to provide complete and conformant files to the guideline.

I could of course run your files in Protégé (though I haver no more
expertise than you have with this software.

But more is that one needs to chech is the vocabulary used is OK with the
one of the Ontology.

I have no RDF and OWL expertise  nor expertise for every formats provided
(Only editors do) to check all the RDF files.
