Matija, I do not have an answer to your question, but this brings up 
something that I have been meaning to address here for a while.

It would be good to look through schema.org for re-usable bits and/or 
facets that should be separated out from particular schemas for easy 
discovery and re-use. I am thinking of common elements like address, 
review, place, time, etc., that could conceivably combine with a wide 
variety of entities and that should be available to schema users as 
"universal add-ons" in their instance data.

In the library world our classification systems make use of "facets," 
some of which are entirely "free-floating" (e.g. can be used with any 
other term), and some of which are restricted to certain parts of the 
classification scheme. These are not added to the classification scheme 
as such but are only implemented in the assignment of classifications to 
particular items.

At the moment, schema.org takes a class/sub-class approach to sharing 
properties. This is not in conflict with the use of facets, and in fact 
library classifications combine hierarchical arrangement with the use of 
facets.

Exactly what should be a "facet" is hard to define theoretically, but a 
good clue is when the same elements or patterns begin to appear in 
separate schemas.
