Subject: NEW Issue - Locating the services by Binding

Please defer discussions on this issue until a time this issue is accepted and is assigned a number.

Description:

In the current specification the Probe message allows the clients to locate Target Service by Types (WSDL portType [WSDL 1.1]) and Scopes. The Types (portType) defines “what” for a web service endpoint; what kind of data is communicated by the service. The Binding (WSDL Binding [WSDL 1.1]) defines “how” part for a web service endpoint. It is often necessary to locate the service endpoint that support say, “SOAP http” binding. Like locating the service by Type, the protocol needs to support locating services by Binding.

Proposed Resolution:

The portType name in the WSDL identifies the operations, messages and message parts supported by the service endpoint. Similarly a Binding name in the WSDL identifies the transports, encoding and policies used by the service endpoint. Probe message in addition to the Types and Scope would include Binding (name). The Binding (name) would be an additional metadata included by the service when it sends a Hello, ProbeMatch or ResolveMatch message.

Attached is the “wsdd-discovery-1.0-spec-wd-01” document with change markers.
