Party

SteveA: Phillip, please correct me if I'm wrong here.

A Party is defined as a role or organisation.

A Party Object is an object that is meant to play a part in one or more ZPatterns frameworks. In implementation terms, it is any Zope object that supports propertysheets.

Each framework is responsible for one (or more) of the propertysheets on a Party Object.

This is similar in principle to what ObjectSpace are doing with their "Facets" approach to separation of concerns.

Achieving Synergy, ObjectSpace's Voyager ORB 3.0

(See under the heading "Dynamic Aggregation", 1/5 of the way down the page.)

I just mention this because I worked with ObjectSpace?'s Voyager product for a while, and it helps me to understand new ideas in terms of familiar ideas.
