Subject: FW: Request for help/information: Comment on Model for Policy (link to WS-Policy)
Apologies for cross posting in advance: During the last and final public review of
the OASIS Reference Model for SOA, we encountered a comment that we feel is
best addressed elsewhere, possibly via one of the WS-* specifications. The RM
for SOA is a high level abstract model for Service Oriented Architecture
aligned with WS-* and meant to guide architects creating various service
oriented architectures including those for the WS family of technologies. Accordingly,
it discusses the concepts of policy which would guide architects in terms of thinking
about architecture and the inclusion of WS-PolicyAttachment and WS-Policy. We have an open request for developing an
abstract model for policy. Although such is beyond the scope of the SOA RM TC,
we wanted to informally request help on this item from the WS groups. First – are any of you aware of a high
level model, not tied to any specific technologies,that would be suitable for
the commenter to use? If you do, can you please respond back with the URL. Second – if none exists, you may
wish to contact the commenter to discuss this. Thank you in advance. Original Comment: Regarding Specification: SOA-RM
(policy and contracts) --- policy is going to play very important role in SOA.
SOA service first has to be policy oriented, which means that policy has to be
involved from the full life cycle of SOA service development from development
to runtime. Therefore it should be beneficial to develop SOA policy reference
model in which it could define capabilities, policy information model, policy
language/computing, etc. The current version of SOA rm on policy is little
vague. If Users can derive concerete product from SOA policy refence
model, it would be great. <response who=”OASIS SOA RM
TC”> 1. The TC agrees regarding
the importance of policy and the RM includes numerous mentions of policy and an
in depth discussion in section 3.3.2. While an SOA policy reference model
may be of value, it is beyond the scope of the current effort. 2.
This TC recognizes that there are several other organizations that are
developing standards, specifications around the concept of policy. We
would like to forward this comment to them for their consideration to include
some form of reference model in their work. We will forward this comment
to various WS groups and the W3C who are working on the issue. 3.
The subcommittee working on our Reference Architecture for SOA will also likely
provide further clarification on the concept of policy with respect to SOA in
their work. </response> ------ |
