ITU-T X.1255 PDF

Discovery of identity management information deals with the fact that one must have the ability to obtain relevant information about identifiers, including those utilizing e-mail address syntax and those that are URLs, as well as persistent identifiers. Such discovery is a key element for enabling interoperability across heterogeneous information systems.

The scope of this Recommendation is for a framework that:

• enables the discovery of identity-related information and its provenance, including information being identified such as services, processes and entities;

• enables the discovery of identity-related information attributes including, but not limited to visual logos and human-readable site names;

• enables the discovery of attributes and the functionality of applications;

• describes a data model and a protocol to enable meta-level interoperability for representation, access and discovery of the information referenced above in heterogeneous IdM environments.
