Web Services Composite Application Framework (WS-CAF) is an open framework developed by
OASIS. Its purpose is to define a generic and open framework for applications that contain multiple services used together, which are sometimes referred to as
composite applications. WS-CAF characteristics include interoperability, ease of implementation and ease of use.
Scope
The scope of WS-CAF includes:
* Provision of
WSDL
The Web Services Description Language (WSDL ) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also ...
definitions for context, coordination and transactions.
* Message formats will be specified as
SOAP

headers and/or body content.
* The specification is to be programming language-neutral and platform-neutral.
* Demonstrated composability with other
Web Service specifications
Web most often refers to:
* Spider web, a silken structure created by the animal
* World Wide Web or the Web, an Internet-based hypertext system
Web, WEB, or the Web may also refer to:
Computing
* WEB, a literate programming system created by ...
that are being developed as open, recognized standards
* The goals of promoting convergence, consistent use, and a coherent architecture.
* Support composability as a critical architectural characteristic of Web service specifications. WS-CAF and WS-Context are targeted to become building blocks for other Web service specifications and standards.
Input specifications
The WS-CAF accepts the following Web services specifications as input:
*
WS-Context
* WS-Coordination Framework (
WS-CF)
* WS-Transaction Management (
WS-TXM)
Benefits
The benefits and results of CAF are intended to be standard and interoperable ways to:
* Demarcate and coordinate web service activities
* Propagate and coordinate context information
* Notify participants of changes in an activity
* Define the relationship of coordinators to each other
* Recover transactions predictably and consistently in a business process execution.
* Interact across multiple transaction models (such as are used in
