Re: W3C SKOS Reference Last Call (3 days left in comment period)

Hi Magnus,

Just to add to what Antoine said, we agree with your position.

The following graph is consistent with the SKOS data model:

ex:A skos:prefLabel "foo"@en ; skos:inScheme ex:MyScheme .
ex:B skos:prefLabel "foo"@en ; skos:inScheme ex:MyScheme .
ex:A owl:differentFrom ex:B .

However, note that such data will probably not be compatible with some
existing thesaurus software.

Regards,

Alistair
