New term request/OOSTT representation: ethnic category information

[mbrochhausen]

The TIPTOE project required the term "ethnic category information (content entity)". This term was already modeled by Emma Chappell during a summer project for OOSTT and is part of the last OOSTT release. We are happy to turn this term over to OMRSE or help create a new term in OMRSE. The current definition in OOSTT is "An information content entity that is about the categorization of an individual's background as it is connected to a geographic region and the shared cultural practices of that region."

Maybe we can discuss this during an OMRSE meeting.
