Dear WSDM TC Colleagues,
Heather (TC Member hat on) and Homayoun were responsible for the
outstanding recommendations on determining the Web services platform
for WSDM's specifications. The immediate and urgent
specifications/technologies that needed to be recommended were for:
- Addressing
- Notification
- Properties/Attributes
- Metadata (descriptive information about the manageability
interface)
We would like to recommend the Web Services Resource Framework as the
specification solution for 3 of 4 of these urgent needs. Metadata is
yet to be addressed. So specifically, we would like to recommend:
- WS-Addressing for Addressing
- WS-Notifications for Notification
- WS-ResourceProperties for Properties/Attributes
We feel that in order to achieve our aggressive March 0.5 specification
dates, we need to leverage specifications already written, which are
targeted for standardization, and supported by multiple vendors.
We would like the TC to read these specifications in detail for the
February F2F and be prepared to discuss them during the WS-Resource
Framework session and vote to approve/disapprove use of them by our
specifications.
Heather (Chair hat on) and Winston propose that we navigate the the
pre-submission state of the specifications as follows:
- WSDM 0.5 specifications - subset of functionality, identity,
metrics, state, and
simple notification.
Since this is a draft specification, it is more
acceptable for us to reference/require specifications which are not yet
standards, or submitted to standards. For expedience, we can reference
to 1.0 pre-submission versions of these specifications.
- WSDM 1.0 specifications - complete functionality of WSDM,
including
operations, configuration, security, Relationships, tbd. This is a
final version of the specification and should not be dependent on
specifications that are not yet submitted (although not finished going
through standardization) to a standards body. All specifications we
depend upon would need to be submitted by that time.
If any of these specifications are not
submitted for
standardization by the time we start the 1.0 work, an alternative
approach will be selected. Realistically, I
think the TC is looking (Heather's best guess) at a July delivery based
on the outstanding work and hard questions to be worked through.
- WSDM 2.0 specifications - revised specification to accommodate
and
leverage the final, standardized versions of WS-Addressing,
WS-Notifications, WS-Resource Properties, WSDL 2.0, and other
specifications we feel are relevant (possibly Policy, etc.).
We would like the TC to consider this delivery plan and accommodation
of
specification dependencies and standardization and be prepared to
discuss and approve/disapprove it at our February F2F. The WSRF
specifications can be located under:
