In the use cases I know about thesaurus or taxonomy publishing, you want
several publication supports:
- xml/skos file to be downloaded
- sparql endpoint to query the controlled vocabulary
- html version for search engine and human navigation

For each publication you want to provide all the semantic information in
the most reusable way. It seems the best way to provide the semantic of a
controlled vocabulary publish in html pages would be to use schema.org if
you could find the proper class and properties.

Find here a data.bnf.fr page about a concept belonging to the Rameau
thesaurus, it has no schema.org annotations, as there is no such properties
avalaible today in schema.org, but for the related pages about works and
persons it was possible to map part of the frbr properties into
schema.orgproperties and then to publish more semantic in the html
concept : http://data.bnf.fr/13319064/science_politique/
person classified with the concept :

"Science_politique" deserve the same chance to be well described in a web
page as cookie recipe or a song.

As you see in the data.bnf.fr it, there is no more complexity for a user to
understand a page about a person, a work or a concept.

data.bnf.fr also publish the rameau thesaurus as xml/skos files as it
publishes the works as xml/rdf files using a bnf ontology mainly based on
