The Metadata Service: Distributing Trust in AAI Confederations
The Metadata Service (MDS) was developed in GÉANT2-JRA5 in order to support the dynamic establishment of trust relationships between members of a confederated authentication and authorisation infrastructure (AAI) such as eduGAIN.
The necessity for dynamic distribution of metadata among members of an AAI confederation will be described, together with the way in which the Metadata Service provides this functionality in eduGAIN. The MDS concept involves centralised storage of information as well as distributed publishing and trust. Since it employs standard SAML 2.0 Metadata, the MDS could also be used in other SAML-based infrastructures.
