Every type page for a type that was added via a collaboration should show
some acknowledgement of an external source. That includes the medical
vocabulary we added
http://blog.schema.org/2012/06/health-and-medical-vocabulary-for.html

For example, http://www.schema.org/Muscle says 'This class contains
information contributed by WikiDoc <http://wikidoc.org/>.'

This information is available in RDFa as part of the dump at
http://schema.org/docs/schema_org_rdfa.html ... but we've not yet added it
to the per-property pages.

If no external contribution is mentioned, then the vocabulary was part of
the original release in June 2011.

Hope this helps,

Dan
