Informed Control Inc. provides open source proof of concept implementation of schema retrieval for the Identity Metasystem
2007 April 7
Informed Control released today the first version of the Schemat Consumer, a proof of concept research implementation of attribute type metadata parsing.
The specifications "Identity Attribute Metadata" at http://openid.net/specs/identity-attribute-metadata-1_0-01.html and at the Identity Schemas Wiki http://idschemas.idcommons.net/moin.cgi/MetaData describe how metadata of identity attributes can be represented using RDF. Online structured metadata provides applications and developers with additional information about unfamiliar attributes. Elements of metadata might specify, for example, the syntax allowed for values of that attribute, or how one attribute relates to other attributes.
The Schemat Consumer provides applications in an identity metasystem with a simple Java API for retrieving the metadata of URI-named attribute types.
More information on the Schemat Consumer can be obtained at the ldap.com schema ontology page.
