Now I understand much better, that this will mainly always be an internal reference for Renault, but you need help with existing linked vocabularies in the Automotive domain, and want to really see the work of others with some "reference vocabulary", in order to ensure that your work is fruitful. Completely understand that. As I said, many of the classes of things or "terms" that you are asking for in an Automotive vocabulary are already described as Entities in Freebase, and Dbpedia, etc, and many of those Entities are already linked to SKOS through a vocabulary equivalent type in Freebase, btw... for instance, your need for a "sunroof" class, is already there and linked to SKOS (and through the GX vocabulary project, which was an early Google product classification and still used internally) : https://www.freebase.com/m/03xtqh has an equivalent SKOS Concept of "sunroofs" https://www.freebase.com/m/0ggjrtp in the GX vocabulary scheme. Beyond Freebase and Dbpedia, you can also search through existing linked open vocabularies through OKFN's service : http://lov.okfn.org/dataset/lov/search/#s=automotive There you have to sort of "know" what kind of classes might be related, or might be called by some alternative label...so some discovery and intuition is sometimes needed on LOV search to find what your really after...and typically it is easiest to just broaden your criteria...in this case, just the term "automotive". Francois, once you and Renault do your internal reduction work, and provide a data dictionary for all, then I would be happy to go through it and make sure that Freebase has all the necessary linked entities with SKOS Concept equivalents that you will need to produce better Schema for us as a proposal on Schema.org and overlapped with VSO. -- -Thad Thad on Freebase.com <http://www.freebase.com/view/en/thad_guidry> Thad on LinkedIn <http://www.linkedin.com/in/thadguidry/>
