Hi all:

The new element in schema.org and a few properties taken from SKOS would not prevent anybody from publishing a thesaurus in a proper Linked Data way, fully based on SKOS, with just the schema.org classes and properties attached in parallel.

There is no either or, and we should keep in mind that the goals of advancing the idea of the "Semantic Web" or "Linked Data" and the goals of schema.org and its supporters are related, yet not identical.
