What are the thoughts on URI's? Should they be considered as Identifiers as well?
external-ids can be mapped to URIs using a URI pattern defined on the respective property. Similarly, external-ids can be mapped to URLs for linking. URL and URI would often, but not always, be the same.
If a property commonly contains URIs, I would suggest to use the url datatype instead of the new external-id datatype. Technically, this is incorrect since not all URIs are URLs, but I think in practice that should not pose a problem.
