The basic idea is this... I am =andy, you are =steve, I can create any number of directed, typed, relationships to you by using the extensibility of the =andy namespace....
=andy*(=steve) establishes a generic relationship.
=andy*(+friend)*(=steve) establishes a friend relationship.
=andy*(+trusted)*(=steve) establishes an actionable relationship.
Let me point out the thing that I think are cool about this...
- These entries MUST have been added and/or removed by the entity that controls the =andy name space.
- Typed relationships can take advantage of the 'dictionary' space (xris that start with '+') and therefore solve a lot of the semantic mapping issues.
- By creating this entry in my name space this relationship has its own i-number, I have very literally reified the relationship. The relationship can have metadata, services and any other quality of a top level entity.
- The target of the relationship can USE this identity; =Steve can assert =andy*(+trusted)*(=steve) as their identity... the fact that xri resolution for this succeeds 'prooves' that =andy established the relationship... You can xri resolve =steve for whatever flavor of authN service that you are interested in so the 'user' can 'proove' they are =steve... I AM =steve who has a (+trusted) relationship with =andy.
- Group management IS relationship management =andy*(+family)*(=richard).
- Relationships are STRONGLY directed. An assertion about a relationship with =steve means only as much as you decide to put on it. Did you know that me and Bill Gates are best buddies and that I'm married to Angelina Jolie?
- It is ALL public. Maybe once I have finished reading the ID-WSF Service Discovery Spec I'll have a better idea how to mix and match the public and private parts of this in a more privacy protecting way.
- There is no native xri way to query the graph. Even if I wanted it to be public there's no (currently speced) way to get all of =andy's +trusted people.
- When I sign up for the genealogical service it is understood that write rights are granted to =andy and =andy*(+family)*($children) and read rights are given to =andy*(+family)*($descendants)
- I can send a message to =andy*(+trusted)*($all)
We must not get confused between the world and the map of the world. It's great that with todays technology we can create these interactive maps that let you:
- show all the houses and the roads
- now turn off the roads and show the electric grid
- now only show the sewer lines
