Woden has made some pretty significant progress but there are some rather 
large work items left including parsing of extension HTTP components, 
validation of extension components and MEPs and adding a URI resolution 
framework. There is also some work that we will need to do on XmlSchema 
and may tests we need to create in order to validate Woden's 
functionality. I am willing to help, especially with work that needs to be 
done to Woden itself. I'm not sure how much time I'll have in the next 
couple months to contribute directly to Axis.

>At present, Woden does not parse WSDL 1.1

True. We've had some discussion about how to support both WSDL 1.1 and 
2.0. Woden did receive an initial contribution of the WSDL4J source. 
(AFAIK Axis using WSDL4J for WSDL 1.1 parsing - correct me if I'm wrong.) 
The long term plan may include merging this code with the WSDL 2.0 code 
and creating one package that supports WSDL 1.1 and 2.0 but it's too early 
to say if and when this will happen. We are of course willing to listen to 
suggestions and happy to receive contributions. As it currently stands, I 
think option 1 makes the most sense. The WSDL 1.1 - 2.0 conversion 
utilities do not handle 100% of WSDL 1.1 cases and I don't want to see 
Axis regress because of an implementation detail.

I think it's also important to point out that one of Woden's goals is to 
answer the W3C WSDL working group's call for implementations. Obviously 
Woden can't completely answer the call so we need Axis to be able to 
achieve this goal. Also, the plan is for Woden to declare an API. This 
can't happen until we receive feedback from clients. Integration with Axis 
should allow for the type of feedback we need from an initial adopter.

Getting the dialog going between Axis and Woden is a great first step in 
achieving goals for both projects. Thanks for starting the conversation.

[axis2] WSDL 2.0 CR work

(Woden folks - please leave the [axis2] prefix on the subject when 
replying, as folks use that to filter axis-dev mail into separate folders)

Hi y'all!

I've taken an action from the W3C WSDL working group to begin inquiring 
about whether we might be able to get Axis2 integrated with Woden in 
time to use that combination as one of the test implementations in order 
to prove interoperability of the WSDL 2.0 specs.

As WSDL is now in CR, and we're trying to get a test suite together, 
this is clearly an "as soon as possible" kind of thing, so we're 
wondering if people on the Axis2 and Woden teams will have some cycles 
in order to get this going in the near term.

The test suite we end up with is going to have at least two parts - one 
involving parsing WSDL documents, which is pretty much covered by Woden, 
and the other involving on-the-wire tests of messages described by WSDL 
documents, and that's where Axis2 comes in.

At present, Woden does not parse WSDL 1.1, and WOM does not parse WSDL 
2.0... :( Therefore it's not just a matter of unplugging WOM and pluggin 
in Woden.  So in order to get this working I see several possible 
directions we could take:

1) Use Woden to parse WSDL 2.0 documents, and then build a connecting 
library which builds WOM objects out of Woden objects.  PRO: none of the 
rest of the Axis2 code would need to change.  CON: the shim layer would 
be throwaway code.

2) Add WSDL 1.1 parsing functionality to Woden.  PRO: This is where we 
really want to be long-term.  CON: lots of effort.

3) Switch over to Woden even without WSDL 1.1 parsing functionality, and 
use the W3C's WSDL 1.1 -> WSDL 2.0 XSLT in order to do WSDL2Java with 
1.1 documents in the meanwhile.  PRO: probably the minimum amount of 
work.  CON: doubtful all WSDL 1.1 documents would work, and there's a 
danger we'd fail on some popular services.

Are there others?

We're looking for thoughts, ideas, and ideally people who would be 
willing to step up and help with this process in some way.  If you reply 
please cc both axis-dev and woden-dev.
