Re: Proposal for new Schema.org mark-up: Vacation Rentals

Thank you for the example Martin, very useful.

Question: As you describe, with GoodRelations we can describe 99% of the
vacation rental attributes. What's the 1% missing? Why do we have Schemas
for Hotels, Motels, Hostels and B&Bs then?

My only concern is that through GoodRelations, we can describe almost
everything though the mark-up but with the absence of a Schema mark-up for
Vacation Rentals we aren't "grouping" the mark-up like the other
accommodation options - am I missing something here? With GoodRelations we
can describe accommodation in general but we don't specify industry

Thank you!
Yannis
