Vocabulary to describe Information cards. See also I-Card.

Information Card (aka i-card) technology is defined by the OASIS IMI TC. It is a standard way to represent a person's digital identities using a card metaphor, XML card formats, and associated SOAP and HTTP network protocols. See also I-Card.

Note: in CDM multiple inheritance is allowed: any single entity may be a member of multiple classes simultaneously.

M-Card Attributes

Shown below is an example of an instance of an m-card. For simplicity this m-card has only a single supported claim, "LastName". The entity shown in the center of the card is a cache of what is returned by the STS in response to a request for a display token.

Example m-card

Note: There is an error in the above diagram the DisplayTokenEntity should have been modeled in the Persona data model (thus identity:surname would have been transformed into its equivalent in PDM.

Card Axioms

  1. For any M-Card: The value of any of the above "supported" claims attributes is considered to be a cache of the most recent value of these claims as fetched from the m-card's STS
