I don't recall Gil getting Bob's permission to go to Australia
20:43:25 [dug]
clearly, he was out of order
20:47:49 [Katy]
Bob: Presume 8176 will stay until next meeting.
20:48:23 [Katy]
Gil: 8284 Text in WSDL 1.1 not consistent with schema.
20:48:39 [Katy]
Bob: One of problems was BP restricted to HTTP and SOAP 1.1
20:49:20 [asir]
20:49:32 [Katy]
Gil: Need carefully crafted text.
20:49:35 [dug]
Topic: 8284
20:49:42 [Bob]
ack asir
20:50:03 [Katy]
Asir: we have a bunch of ws-ra spec wsdls already and we can already build BP compliant.
20:50:33 [Katy]
Gil: We are talking about references to WSDL 1.1 in our specs when WSDL 1.1 is broken
20:50:44 [trutt]
20:50:53 [Katy]
Asir: but why does this matter as our WSDLs are ok
20:51:08 [asir]
... also our operation descriptions are okay
20:51:19 [Bob]
ack tru
20:51:37 [gpilz]
here's what I'm talking about: 4.7.12 Describing headerfault Elements There is inconsistency between WSDL specification text and the WSDL schema regarding soapbind:headerfaults. R2719 A wsdl:binding in a DESCRIPTION MAY contain no soapbind:headerfault elements if there are no known header faults. The WSDL 1.1 schema makes the specification of soapbind:headerfault element mandatory on wsdl:input and wsdl:output
20:52:30 [Katy]
Asir: Our WSDLs are BP compliant so why does it matter
20:53:09 [Katy]
Gil: We should reference a version of WSDL 1.1 that is BP compliant - where the inconsistencies have been addressed
20:53:19 [dug]
20:53:27 [asir]
WS-RA specs don't define any headers
20:54:21 [dug]
20:55:34 [dug]
so a BP compliant WSDL isn't WSDL 1.1 compliant?
20:56:20 [asir]
20:56:37 [Katy]
Bob: How about we keep the normative ref to WSDL (same as BP) but mention that we would expect implementations to be conformant to the requirements of BP?
20:56:54 [Katy]
Asir: but wouldn't we need to list the requirements
20:57:06 [Katy]
Bob: It would be up to the implementer to choose
20:57:17 [Katy]
... depending on what they were doing
20:57:27 [Katy]
Asir: We would like to consider this
20:57:58 [Katy]

TOPIC: Issue 6463
21:01:15 [Katy]
Katy: Described 2nd proposal
21:01:49 [dug]
21:01:53 [Katy]
Asir: We like the proposal but have some further changes marked up
21:02:04 [trackbot]
Could not create new action (failed to parse response from server) - please contact sysreq with the details of what happened.

Could not create new action (unparseable data in server response: local variable 'd' referenced before assignment) - please contact sysreq with the details of what happened.
21:02:04 [Katy]

I'd like more time to review Asir's proposed edits

21:03:41 [dug]
email site is ok- main w3 site is slow/down

21:04:13 [dug]
e.g. bugzilla is down for me

Dug: Please could we have a marked up copy
21:08:34 [Katy]
Ashok: I made some comments on the syntax - in particular the layers of wrapping needed in the Metadata
21:08:46 [Katy]
... could be a new issue
21:09:18 [Katy]
... but this is related to how the policy is attached to the endpoint so I am wondering what to do with these concerns
21:09:57 [asir]
21:10:15 [Bob]
ack ashok
21:10:19 [Katy]
... Issues are: 1) schema url is duplicated
21:10:33 [Katy]
... 2) We have 3 layers of wrapping

Asir: The above is just that the identifier is a hint for what is in the WSDL - the identifier is optional

21:13:26 [Katy]
Ashok: Why not take out mex:Metadata?
21:13:58 [Katy]
Asir: Because the mex:metadata may be embeded in transfer response, epr or mex
21:14:31 [dug]
21:14:43 [Katy]
... transfer requires one wrapper which is first wrapper in resource representation
21:15:03 [Katy]

Dug: The mex arwpper in transfer is only useful in transfer when all metadata is wrapped in one blob
21:17:33 [Bob]
ack asir
21:17:38 [Katy]
... if you are moving mex metadata documents it provide consistency
21:17:58 [dug]
21:18:22 [Bob]
ack dug
21:18:33 [Katy]
... but other metadata - wsdl, schema - does not have wrapper so ws-t, http do not get consistency through mex metadata
21:18:40 [asir]
21:19:17 [Bob]
ack asir
21:19:17 [Katy]
dug: I think common usecase would be 'give me your wsdl' where the mex:metadata is not require

Ashok: We have not reached agreement on the points that I raised
21:26:14 [asir]
21:26:18 [Katy]
... Issue is: The syntax of attaching mex matadata should be simplified
21:26:35 [Katy]

21:28:56 [Bob]
ack asir
21:29:01 [Katy]
Bob: As this is a substantive issue, my recommendation would be to open it now
21:29:03 [dug]
21:29:38 [Yves]
if it's just syntax, that's not a major change
21:29:57 [Katy]
Asir: This is not a huge issue - no new feature
21:30:01 [gpilz]
21:30:05 [dug]
its a bit more than syntax

he really wants to be on the queue :-)
21:31:59 [Bob]
ack gp
21:32:09 [Katy]
dug: The usecase is when the metadata is something as simple as wsdl - it is not clear whether this is just a wsld document directly under wsa:metadata or whether it is wrapped in a mex:metadata wrapper. That needs to be cleared up.
21:32:27 [Zakim]

Gil: I don't think it's advisable to leave this until last call. We should focus on it now

ack asir

Asir: Embedding WSDL directly into ws-addressing metadata - was taken out as there was no implementation experience

21:39:45 [asir]
21:40:03 [Zakim]
21:40:03 [Katy]
Ashok: Issue 7728 may include this and would be a good location for discussing this issue
21:40:45 [Yves]
same as Bob, don't want new issues to postpone LC indefinitely
21:42:25 [Katy]
ACTION: Asir to write up proposal with changes incoporated
21:42:25 [trackbot]
Created ACTION-130 - Write up proposal with changes incoporated [on Asir Vedamuthu - due 2009-12-22].

21:43:27 [Ram]
Resolve with new proposal

Dug: This is about the mex:all dialect uri
21:44:15 [Katy]
... but Gil also notices (8297) has a def of mex dialect from getmedata operation that is wrong

"When this repeating OPTIONAL element is present, the response MUST include only Metadata Sections corresponding to metadata specified by the combination of the URI, Identifier and Content attributes of each of the Dialect elements. For each Dialect element if there is no metadata for that combination of attributes then the response MUST NOT include any Metadata Sections for that Dialect element."

dug: as there's an xs:any element, we can't prevent multiple mex:md anyhow so there's no point in making it unique
21:53:09 [Bob]

21:53:27 [dug]
21:53:42 [Katy]
Gil: having individual metadata:section elements in each mex:metadata is no different from multiple metadatasections in one mex:metadata

mex:Metadata(A, B) == mex:Metadata(A) + mex:Metadata(B)
21:54:21 [Bob]

Asir: What we are actually discussing is optimal syntactic form. We should have use case for multiple
21:54:52 [Katy]
Dug: I am happy to write up Gil's issue
21:54:59 [gpilz]
21:55:10 [Yves]
why can't multiple MEX entries be alternatives and not complement each other?
21:55:25 [Yves]
if you have no control, you have no control on the meaning
21:55:31 [asir]
agree with Yves
21:55:34 [Katy]
Asir: this doesn't fix it. I would like to understand a motivation. WS-T fixes the extensibility so why can't we
21:56:10 [Katy]
Dug: ws-t isn't the same problem
21:56:19 [dug]
21:56:39 [asir]
21:57:08 [Katy]
Gil: There are advantages in having multiple mex:metadata sections in an EPR if multiple components are working on different sections

ack gpi

... I don't understand the motivation of imposing a restriction instead of just having one
21:57:58 [Bob]
ack asir
21:58:21 [Katy]
Dug: mex:medatadata has extensibility points. Having multiple mex:metadata elements allows folk to have different extensibility elements for each - not restricted to one
21:58:53 [Katy]
Asir: Gil's point is a programming API - a serialisation issue so it's not relevant
21:59:32 [Katy]
... I would like to see a proposal written up with reasons for this function
22:00:02 [gpilz]
22:00:10 [dug]
22:00:23 [Katy]
Yves: If there are multiple mex:metadata elements, then there would be no way of indicating the relationship between the various mex:metadatasections
