It represents a first step toward languages that try to balance expressive power and simplicity of use. Thus, PSC is more intuitive and easily understandable than the traditional temporal logic, such as linear-time temporal logic or computation tree logic...
The Web Services Choreography Description Language (WS-CDL) is a specification developed by the W3C that can be viewed as a blueprint for the development of end-point services. Considering that it is the W3C candidate recommendation for web service choreography, it is worth providing a systematic approach for its modeling, analysis and verification. The Unified Modeling Language (UML) is the de facto...
