WS Choreography Description Language (WS-CDL)
WS Choreography Description Language (WS-CDL) is an XML-based language that is used to describe and specify the interactions between web services in a choreography. It is a standard that is part of the WS-* stack of web services standards, and it provides a way to define the structure and behavior of choreographies.
WS-CDL provides a formal way to describe the interactions between Web Services, including the messages that are exchanged, the order in which they are exchanged, and the conditions under which they are exchanged. It allows for the creation of complex, multi-party choreographies, and it supports a range of message exchange patterns, including request-response, one-way, and asynchronous.
Some of the key features of WS-CDL include:
- Formalism: WS-CDL provides a formal way to describe choreographies, which makes it possible to verify their correctness and ensure that they meet the requirements of the business process.
- Flexibility: WS-CDL is highly flexible and can be used to describe choreographies that involve multiple parties, even when those parties have different roles and responsibilities.
- Integration: WS-CDL can be integrated with other web services standards, such as WS-Addressing and WS-ReliableMessaging, to provide a complete solution for web services choreography.
- Reusability: WS-CDL descriptions can be reused across different implementations and platforms, which makes it possible to create interoperable web services that can be used across a wide range of applications and environments.
WS-CDL is an important standard for web services choreography, as it provides a way to specify and describe the interactions between web services in a clear, formal manner. This makes it possible to create complex, multi-party choreographies that are reliable, flexible, and interoperable across different implementations and platforms.
