Dear Martin,

I have checked the EBUCore instance with different tools and couldn't find errors.

I would need more information than this to try and fix errors what Pellet apparently detected. I'll start by checking the collection issue.

Why do others tools not find these errors? Is Pellet the absolute reference? Why?

Regards,

Jean-Pierre

Objet : Checking MA mapping examples

Dear all,

I have finished checking all mapping examples with Protégé and Pellet.

Here is my list of issues:

-          Missing comment line containing creation and version information (cf. [1])

-          In some cases, datatype values are represented as strings rather than xsd:decimal

-          Sme datatype values  include  units, which should be removed (eg. Kbps)

-          In 3gp-Example-v4.rdf the xml:base directive should be removed in order to import the ma ontology correctly

-          According to Pellet, the EBUCore example is inconsistent. Possible reason is that  at least one instance is a member of two disjoint classes (MediaResource and Collection).

-          Cablelabs 1. 1 example is not RDF valid
I propose to discuss these issues during the upcoming F2F meeting.
