Cultural heritage domain (Museums and collections)

Hi,

I'm searching for a public ontology/vocabulary to represent knowledge from
the cultural heritage domain, more especifically knowledge to describe
cultural institutions (mainly museums).

The idea is to generate and publish Linked open data about Museums in Spain
(describing their tipology, who is responsible for them, address, services,
prices, etc.), link them to their available digital collections (described
using dublin-core vocabulary) and finally link them to other Linked data
such as DBpedia, geolinkeddata, etc.

I would really appreciate any help on this subject. Is someone working or
has worked on something similar? Are there already good resources to work
with this knowledge domain? Any linked data

Cheers,

Daniel Vila
