What won't we do with it? [Tribe.net: FOAF]

In answer to Tom's question "what won't we do with FOAF" I can say that FOAF does not include authentication, security or privacy controls. It is up to each vendor, developer and system to provide those features.

FOAF is simply an object wrapper around whatever profile data you wish to store. Any kind of unique identifier can be inside a FOAF file. FOAF is just a stnadard way of FINDING profile data, which is then addressed and pointed to - in a standard way. That's it.
