Simple motivating test cases linked from webschemas wiki would be useful. There are two important cases w.r.t. schema.org: (i) multiple schema.org types (ii) combination of schema.org and types from elsewhere. There's a related issue around the miniskos discussion, which is how to use externally enumerated sets of categories (which might not best be modeled using types), e.g. food cuisines. But we can cover that separately. Note also that anything below LocalBusiness already counts as both a Place and an Organization. cheers, Dan > Having that could make process of fixing those bugs more straight forward > for people developing those tools! > > >
