Tasked with designing a simple identity framework for the Augmented Social Network, a good place to start is a shared basic vocabulary.

• (optionally signed) information about an identity (tech speak: P := [[Abstract_URI, Key, Value] Sig]) note that Key and Value can be defined within a (community) namespace
• profile objects are entities and can be named (tech speak: profile objects are first class objects)
• profile objects can have access rights attached to them

ENTITY

any object (person, thing, profile, reputation, etc.)

IDENTITY

a unique and persistent (within a community) name for an entity

PROFILE OBJECT

PROFILE

a collection of profile objects created by, or about, an identity

REPUTATION

a usually domain (key) specific (and nearly always fuzzy) calculation of an identity's reputation or standing (usually within a community)

CERTIFICATION

a signed authentication by a trusted (reputable) third party

Thus, these all may make up part of my profile:

Reputations are often calculated within a domain such that transitive trust issues can be more easily resolved, e.g., a process calculating Owen's reputation as a networker may tap into Fen's profile during its lifetime.
