RE: ID primitive

I think the goal of an ID is:

*         Unique - not-named-based identification

*         Key - able to be used as a primary key

*         Persistent - does not change unless a key large scale change to the object warrants (rare)

*         Efficient - does not consume large bandwidth to distribute

*         Informative - can potentially contain some high level information about the object to circumvent always having to complete a round trip to the content service to determine if the object is of interest (country code, basic type - point, line, area, ownership  - private, public)

Subject: ID primitive

On today's Teleconference the ID primitive was briefly discussed.  Karl Seiler recommended that we look at what data should be encompassed in a POI's idea. Does it encompass geodata? Other Data? Surely there is something better than a 64bit number.

While I dont have a solution I do have a few thoughts.

With the assumption that the ID is permanent, can it include info that is not permanent? For example if there is a POI for a Circus and we include Geodata in the ID does that imply that circus can not move? If as discussed a POI has a relative location how is that capture?

Is there a decent permanent piece of information that can be added to the ID? Or is location fine except for the edge cases above?
