Subject: RE: [wsdm] W3C submission Ws-addressing version, call for objections

Just to make sure we understand what this would
mean:
1) All the EPRs in properties, messages and events
that we define are moved to the 8/2004 namespace. This is not
hard.
2) All the EPRs in the messages and
properties defined by WS-RP and WS-Notif are moved to the 8/2004 namespace.
This means that we cannot use the schemas provided by WS-RP v 1.2 and
WS-BaseNotif v 1.2. That for example the WSDL definition for something like
the "subscribe" operation of WS-BaseNotif is not written anywhere and has to be
generated by WSDM implementers by looking at the definition in the WS-BaseNotif
spec and changing the QName of one of its element. Unless we provided "updated"
versions of all these WSDLs in our spec. This is a lot
harder.
Another option is to move to 8/2004 for the EPRs that we
define (bullet -1- above) but stay with 3/2003 for the EPRs defined by WS-RP and
WS-BaseNotif (not doing bullet -2- above). Which would solve some problems (we
can base our implementations on any WSRF 1.2 and WS-Notif 1.2 compliant
implementation like GT4) but also introduces confusion. Especially when we
consider WS-ServiceGroup because then you need to translate the EPR of your
manageability endpoint from 8/2004 to 3/2003 before adding it to the service
group. And if you were to for example express that you have a relationship
with a subscriptionManager WS-Resource (returned by invoking "subscribe" on
a notificationProducer) you would have to translate the EPR of this resource
from 3/2003 to 8/2004. etc...

This seems reasonable to me.
I recommond that we make WSDM MUWS
dependent on the WS-Addressng submission to the W3C.
Any
objections?

I
believe it is preferable to move WSDM to reference the W3C member submission
version of WSA.
I believe that WSN and WSRF are
doing that anyway.
In WSRF, issue WSRF43 [1] was
resolved at the Oct F2F, with the resolution being:
"Update specifications that reference WS-Addressing to
refer to the version submitted to the W3C. This includes all namespace
references and examples. Make sure to update the WSDL and schema in addition to
the specification text. The version to reference is the August 2004 version
submitted to the W3C."
In WSN, issue WSN2.15
[2] was also resolved at the Oct F2F, with the resolution being:
"Agreed Approach: Editors to borrow text from the WS-RF
issue #30 resolution."
Now, WSRF30 is a
slightly different issue (deals with use of wsa:Action MIH), but WSRF30 cross
references WSRF43. I suspect that the resolution to WSN2.15 should
reference WSRF43, but that seems to be a matter we should take up with the WSN
TC.

[wsdm] Ws-addressing
version |
|
What
version of WS-Addressing do we want to reference? The one
submitted
to W3C in August? Or the one used by version 1.2 of the
WSRF/WSN specs
(that'd the March 2003 one, two versions older than
the W3C-submitted
one).
On the one hand it would
make sense to align with the one used by WSRF,
on the other hand it
seems a bit silly for a new spec like ours to
reference such an old
version.
Thoughts?
William
