WSDL 1.2 Binding Changes

WSDL 1.2 Binding Changes

• Sanjiva Weerawarana
• WSDL WG F2F July 2003
• Raleigh, NC

2
Motivation

• Without ltmessagegt we can make WSDL 1.2 bindings
  dramatically simpler

3
Overview

• ltbindinggts in general
• SOAP binding
• HTTP binding
• _at_encodingStylerpc
• General documents

4
ltwsdlbindinggt

• Make _at_interface optional to make binding more
  reusable
• ltbinding namencname interfaceqname gt
• binding details
• ltoperation nameqnamegt .. lt/operationgt
• lt/bindinggt
• If any ltoperationgt elements are present, then
  _at_interface MUST be present
• service/_at_interface MUST match deref(endpoint/_at_bind
  ing)/_at_interface
• Allow ltendpointgt to point to bindings or inline
  bindings
• ltservice interfaceqnamegt
• ltendpoint namencname
• bindingslist-of-qnamesgt
• inlined-bindings
• address-binding
• lt/endpointgt
• lt/servicegt

5
SOAP Binding

• Define default SOAP binding rules
• _at_body goes into ltsoapBodygt
• Each of _at_headers goes into ltsoapHeadergt
• Define new binding element for default rule for
  wsoapoperation/_at_soapActionURI
• Proposal interfaceTNSoperation-name
• Drop ltwsoapbodygt, ltwsoapfaultgt
• Change ltwsoapheadergt add new header or add
  _at_role/_at_mustUnderstand
• Drop _at_type, _at_namespace, _at_localname,
  _at_encodingStyle
• Add _at_mustUnderstand??
• Retain ltwsoapheaderFaultgt update
• Drop ltsoapbindinggt drop _at_protocol
• Change ltsoapaddressgt add _at_protocol
• Cool feature No need to pay attention to
  /definitions/interface/operation/_at_encodingStylerp
  c

6
HTTP Binding

• For _at_encodingStylerpc case
• If types are all simple, then can do HTTP
  GET/POST binding for content-typeform-url-encoded
  
• URL rewriting, POST body,
• Basically s!_at_partfoo!xpath/foo!g
• For other cases
• Natural text/xml binding with input/_at_body as
  input payload and output/_at_body as output payload

Example - Today

• ltdefinitionsgt
• lttypesgt
• ltxsdschemagt
• element-decls
• lt/xsdschemagt
• lt/typesgt
• ltinterfacegt
• ltoperation namencnamegt
• ltinput elemente1/gt
• ltoutput elemente2/gt
• lt/operationgt
• lt/interfacegt

• ltbinding namencname
• interfaceqnamegt
• ltsoapbinding transporthttp/gt
• lt/bindinggt
• ltservice interfacencnamegt
• ltendpoint namencname
• bindingqnamegt
• ltsoapaddress location/gt
• lt/endpointgt
• lt/servicegt
• lt/definitionsgt
