Issue - 72 - Background information about WS-I BP1.0 recommendations on

Hi all,

Attached please find a set of slides which provide a summary and some details about the BP1.0 recommendations on the use of WSDL1.1.

After a preliminary analysis on these BP1.0 recommendations, I feel that we should adopt WS-BP1.0 for BPEL. Below are my observations:

- BP1.0 provides many valuable clarifications on use of WSDL1.1. These clarifications should be reflected in all WSDL examples in BPEL spec

- The following BP1.0 constraints affect portType definitions and should be considered for BPEL

n XML1.0 is mandated for WSDL definitions - OK, that's the status quo.

n XML schema is the only conformant type system - OK, I believe that's also the status quo. BPEL only use XSD for data type definition

n Disallow operation overloading - operation name must be unique within a portType - should be enforced. I don't see anything in BPEL relies on this

n Disallow out-bound operations - OK, that's the status quo

- The following constraints are for bindings, there is no direct conflict with BPEL

n SOAP over HTTP is the only conformant binding -OK, we only provide conformant portType definition, bindings are up to the services implementers.

n Disallows (soap) encoding - OK, same as above

Best Regards,
Kevin

Issue - 72 - What to do with WS-I BP1.0?

Status: open
Date added: 1 Oct 2003
Submitter: Liu, Kevin
Date submitted: 01 October 2003
Document: Specification
Description: WS-I BP1.0 provides clarifications and constraints on the use of WSDL1.1. We need to investigate and decide if BPEL should be aligned with BP1.0. In particular, a few questions need to be answered:

1. Would BP 1.0 be restricting BPEL to the point that some of BPEL's functionality would not be available?

2. Would the fact that BP 1.0 only addresses the SOAP/HTTP binding imply that also BPEL should be limited to that type of binding?

3. Should a BPEL process be offered as a Web service that is BP 1.0 compliant?

4. Would it be fair to limit BPEL use to interacting with BP 1.0 compliant Web services only?
