Let's try to align more closely with GS1's use for products at http://gs1.org/voc/countryOfOrigin ("Code indicating the country of origin of the product.").

Currently http://schema.org/countryOfOrigin seems rather wasted, "The country of the principal offices of the production company or individual responsible for the movie or program.". It should be possible to preserve the original usecase while making this property useful on a greater range of things.
Currently we expect it on: Movie, TVEpisode, TVSeason, TVSeries.

Suggestion: "The country of origin of something, including products as well as creative works such as movie and TV content. In the case of TV and movie, this would be the country of the principle offices of the production company or individual responsible for the movie. For other creative works [ .... TODO].

Issues:

• what should we say about other creative works?
  • http://schema.org/contentLocation "The location depicted or described in the content. For example, the location in a photograph or painting."
  • http://schema.org/locationCreated "The location where the CreativeWork was created, which may not be the same as the location depicted in the CreativeWork."
• For complex or compound products, what to say?
• If multiple countries are applicable, is it reasonable to expect the property to be repeated?
