Lexicon

The Lexicon was developed by the Identity Gang it is a resource for the whole community to have a shared language.The following terms and definitions have been compiled since August 2005. See also Lexicon Goal and Lexicon Style Guide.

1. Agent
2. Claim
3. Claimant
4. Digital Identity
5. Digital Identity Provider
6. Digital Subject
7. Entity
8. Identity Attribute
9. Identity Context
10. Party
11. Persona
12. Relying Party

Rework: We continuously fix bugs in the Lexicon, but I think Persona in particular needs some rework (i.e. shift its definition from being based on DI to being based on DS).

Proposals, Pending

The following links propose changes, additions, deletions, etc. to the lexicon. Nothing has happened on this for a while. The first gen of the lexicon was edited and pushed along by PaulT, but he's not done anything since 2007 on this "v2" effort:

• Federation (a couple of interpretations of such)
• Confirmation (proposed by Eric Norman)
• User Centric
• Identity Issuer (to preplace Identity Provider)
• Service Provider (as a synonym of Relying Party Agent)
• Identity Context -needs to be broadened and woven into the definition of Digital Subject.
• i-card (suggested by PaulT and discussed under a tree at MIT during the June 2006 IdMashup conference. See these notes and i-card in wikipedia)

It is also worth Noting that the ITU Lexicon/Ecosystem group has put forward that it would like to define the following terms. These could change of course but as of April 25 this was the list.

• Identity Management
• Discovery
• Reputation
• Proofing
• Trust
• Asymetric Authentication
• Privacy
• Security
• Anonymity
