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.[1] WS-CAF characteristics include interoperability, ease of implementation and ease of use.


The scope of WS-CAF includes:

  • Provision of WSDL 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 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[edit]

The WS-CAF accepts the following Web services specifications as input:


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 CORBA, CICS, Enterprise JavaBeans or .NET environments).[2]
