WSDL 2.0 Core, Adjuncts and Extensions
This section describes WSDL 2.0 core, adjuncts, and extensions: message exchange patterns, operation safety and styles extensions, SOAP and HTTP extensions.
The original WSDL 2.0 language specification
(published in 2007 at
was divided into 2 parts: Core and Adjuncts:
Core, represented by URI: http://www.w3.org/ns/wsdl
- Defines the core language which can be used to describe Web services based
on an abstract model of what the service offers.
- Defines extension language for these areas:
- Message exchange patterns -
Define the sequence and cardinality of abstract messages listed in an operation.
Predefined patterns are: In-Only, Robust In-Only, and In-Out.
- Operation safety extension -
Adds the "safe" property to Interface Operation components defined in the Core.
- Operation styles extension -
Defines operation styles that can be used to place constraints on Interface Operation components
defined in the Core. Predefined styles are: RPC, IRI, and Multipart.
- SOAP binding extension -
Defines binding language to bind a Web service from an abstract model to a concrete model using SOAP 1.2.
- HTTP binding extension -
Defines binding language to bind a Web service from an abstract model to a concrete model using HTTP.
Later, another extension was added: "WSDL 2.0 SOAP 1.1 Binding"
WSDL SOAP 1.1 Binding -
Defines binding language to bind a Web service from an abstract model to a concrete model using SOAP 1.1.
