Re: Real Estate Ontology/Vocabulary?

Hi Florian,

We are currently developing (have developed) a gazetteer and addressing ontology in the Australian Government (http://linked.data.gov.au) and in a project with a local utility company we are about to extend it with premise level information (i.e. terms that overlap with the requirements of a real estate ontology such as parcel size, bedrooms, bathrooms, accommodation type, energy rating, etc.). Happy to collaborate. Maybe in the context of a W3C community group (https://www.w3.org/community/groups/)?

Kind regards,
Armin

    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.
