Hey, this is great - many thanks for restarting this discussion.

I am very sympathetic to this too. We have several ad-hoc places in
schema.org where categories and code lists could be modeled in a more
structured manner (but without having a full entities/properties
approach). For example, JobPosting job taxonomies, LRMI educational
AlignmentObject codes, recipe and event categories, ... It has also
cropped up in recent discussion around the idea of additional rNews
extensions relating to http://www.bbc.co.uk/ontologies/storyline/

I'm not sure the direct mapping of ConceptScheme to Enumeration works
as intended, but that's a relatively minor point. I imagine some
vocabulary publishers might choose to publish using RDFa Lite + SKOS +
schema.org simultaneously.

Stéphane, on the Drupal front, how much is built-in to the core now
versus handled by one of the countless 3rd party Drupal extensions?
