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

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

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?
