That could make it hard to find the properties you want.  Instead,
schema.org has opted for a single global namespace for properties and
allowing multiple domains per property (notice the URLs are not nested
under the type's URL).  For example, Product <http://schema.org/Product>and
CreativeWork <http://www.schema.org/CreativeWork> share the same "review"
property.


And in the spirit of linked data, shouldn't it be possible to link any two
