Real Estate Ontology/Vocabulary?

Hi,

I am interested in representing different entities from the real estate 
business universe as RDF, as seen through the lens of a real estate 
trading/managing platform. (*)

For now, I would like to represent real estate (apartment/house) with 
assorted entities (garden, parking, ...) and the economic functions 
associated with them (buy/sell/rent/auction/...).

Unexpectedly, I did not find any specialized ontology for that using Web 
search or LOV (http://lov.okfn.org/dataset/lov/vocabs).

There is a de facto XML standard for this (curently only in German): 
http://www.openimmo.de
It's quite rich in terms and concepts but the license does not seem to 
allow transforming it to an ontology.

The closest matches in the SemWeb world are:
1. Goodrelations: 
http://wiki.goodrelations-vocabulary.org/Cookbook/Real_estate
This is ok, but the example barely scratches the surface of what one may 
want to represent. Still the best match.

2. Acco: http://ontologies.sti-innsbruck.at/acco/ns.html#Apartment
Found this mainly by searching apartment. It's not actually about real 
estate trade, but maybe one could use some classes/relations.

3. Schema.org: http://schema.org/Apartment
Same as 2, only found because it describes an apartment class, it does 
not seem to touch the real estate business. (and, as it says on the 
bottom of the page, based on acco).

If I don't find any closer matches, my course of action will probably be 
to start off schema.org's Accomodation classes and define additional 
classes and properties as needed, probably staying on the RDFS level.

My questions are:

* Have I missed anything? Is there an ontology/vocabulary or a 
combination thereof that you think is suitable for the use case?
Is there an international standard I did not see?

* If not, would you recommend a different course of action than I proposed?


Many thanks!

Best regards,
Florian


(*) It's not essential to the question, but for context, I'll add: the 
short-term goal is to publish real estate demand/offer on the Web of 
Needs - e.g. https://matchat.org/ and have them matched automatically.
