WS-CAF

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.

Scope

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

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 CORBA, CICS, Enterprise JavaBeans or .NET environments).[2]
gollark: I generally only interact with modern hardware, and over SSH.
gollark: Well, I'm not, see.
gollark: If I'm on a connection that high latency I can just use mosh, which does some magic to compensate for it on the client, and continue using nano.
gollark: I heard about a project using a USB/VGA adapter as a bad transmit-only SDR.
gollark: Hello, would you like to hear a TCP joke?Yes, I'd like to hear a TCP joke.OK, I'll tell you a TCP joke.OK, I'll hear a TCP joke.Are you ready to hear a TCP joke?Yes, I am ready to hear a TCP joke.OK, I'm about to send the TCP joke. It will last 10 seconds, it has two characters, it does not have a setting, it ends with a punchline.OK, I'm ready to hear the TCP joke that will last 10 seconds, has two characters, does not have a setting and will end with a punchline.I'm sorry, your connection has timed out... ...Hello, would you like to hear a TCP joke?
