Subject: Re: [stp-dev] Discussion on policy support in STP
Johnson,
very good start on the subject, this will be quite interesting to discuss.
Some quick questions:
The description of the policy data model states that the policy model used
is different from WS-Policy or SCA Policy-Framework. Could you explain the
policy metaphor you're referencing a little bit? Am I correct in assuming
that it is more like WS-Policy policy assertion (i.e., describing a single
property) than policy alternative (i.e., combining multiple policy
assertions into an entity that describes many aspects, possibly describing
several acceptable behaviours)?
The metadata attribute in the policy model of the proposal is a WS-Policy
document.
However, we need more than that. Such as the 'Dependencies' attribute as
David pointed out.
Do you propose to actually add a Policy Registry to STP or do you want to
provide the interface definition that an actual registry has to conform
to?
Yes, i was thinking about adding a policy template registry to stp.
Then, policy developers can create policy template and add to the registry.
Regarding the validation issues we have plans to generalize the validation
components that are currently integrated with our (sopera's) editors into
a generic validation framework. Maybe it would be a good idea to
contribute the code directly and work on the generalization together?
Cool. I think the generic validation framework can be used in both design
time (stp) and runtime (swordfish).
How do you express the validation rule? Do you have a policy validation rule
editor already?
I'm looking forward to discussing this further.
best regards
Jerry Preissler

Hi all,
We added the policy editor recently, so it is time to think more about
how to enforce SOA policy during developing and deploying service
component. I wrote a proposal on stp wiki named "Policy Framework in
STP", hope that we can kick off a series of discussions from here on how
to support policy in STP.
