Subject: RE: [soa-rm-ra] Diagramming trust - another take
Ken: I opened the first diagram and was immediately confused. When I "own" a house I have neither goals or constraints (other than paying the taxes on the place) so how does the diagram define the boundary of my house?

Ellis; Francis McCabe; soa-rm-ra@lists.oasis-open.org Subject: [soa-rm-ra] Diagramming trust - another take > After another long talk with Dave Ellis, I am again inspired to try to express some ideas, and this time I come with definitions and diagrams. Goal: a desired set of real world effects Goal may be that the real world effects are realized, avoided, or some combination. Constraint: a specified set of real world effects that an actor is (1) limited from pursuing or being responsible for indirectly causing, or (2) responsible for pursuing Ownership Boundary: the extent of an identifiable set of actors sharing a common set of goals and constraints, and other common entities through which the goals and constraints can be expressed. A given actor may reside within one or more ownership boundaries. There may be agreed upon protocols for interactions that cross ownership boundaries or an actor crossing an ownership boundary may independently need to resolve any mismatches. Reputation: a property of a given actor assigned by other actors based on the accumulated experience experience of the other actors on the extent to which real world effects resulting from interaction with the given actor are assessed as desirable, neutral, or undesirable. Other definitions are needed but I was concentrating on the diagrams that follow.
