Attribute metadata is another aspect of attribute management concerning the exchange of attributes. What is needed is agreement on what the semantics are for metadata. For example, SAML has some metadata for attributes, but much more will be needed as the growth of interoperability of attributes continues. We will need registries for attribute sets/categorization (i.e. IANA), agreement about the semantics, and mappings between sets of attributes having differing semantics
NOTE: Check with John Bradley/OASIS Trust elevation TC regarding where SAML is, and is not, relevant to this report.
