RE: [soa-rm-ra] Action Model One pager.... revised

["Laskey, Ken" <klaskey@mitre.org>]

So I believe the pushback -- certainly from me -- is that the "invoking" is the joint action and what the provider does to realize the RWE is largely unknown and independent of the consumer. 

The unanswered question is whether interactions to establish the EC are also JA.  I'm sure Rex would say yes.  I don't think this is a significant problem or complication because it just emphasizes that most of SOA is dealing in community.  This raises the significance of trust and willingness and the fact that, especially across ownership boundaries, execution context cannot be taken for granted.  Consistent policies and semantic engagement are just as important as getting the endpoint right.  I think this is the message of the ecosystem view.

I am still left with the question of how JA relates to Action.  Right now, I'm leaning toward Action as only being a part of the Action Model and JA being the ecosystem interactions.  That leaves the sticky problem of how action is then the "application of intent".  I cringe at the idea of bringing back service action as what's in the Action Model, but that is a possibility.

So we'd have Action as something general, JA as action between 2 or more actors, and a separate (service) action that is what the consumer asks the service to do to realize the described RWE.

Still not neat and clean but I think the direction we need to go.

Subject: [soa-rm-ra] Action Model One pager.... revised

Hi:
As requested, here is an update of the (slightly more than) one-pager covering the issues of action. This takes into account the main points raised over the last week and – if acceptable – will be used as the basis to reword the relevant parts of section 3

Talk tomorrow,
Peter
