Common claim types

The claim type describes the context of the claim value, meaning that it describes the content of the claim value. In SAML2 and WS-Federation the format of the claim type can be of either URI og URN.

URI format: Uniform Resource Identifier (URI) is an identifier based of a string of characters.
Generic form of URI is: scheme:[//[user:password@]host[:port]][/]path[?query][#fragment]

URN format: Uniform Resource Name is a URI that uses the URN scheme.
Generic form of URN is: urn:<NID>:<NSS> (NID = namespace identifier, NSS namespace specific string)
Example: urn:oid:0.9.2342.19200300.100.1.3
