[Fwd: Re: [stp-dev] Discussion on policy support in STP]
|
Hi all,
I have a few comments and questions on the proposal as well. To make it
easy to relate my comments to the current proposal I've actually put
them on the wiki. You can easily find them by looking for 'David
Bosschaert'.
Sorry to pollute your document, Johnson, but I thought this would be the
clearest way of communicating them.

Cheers,
David

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)?
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?
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?
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.
