Abstract :
The description of choreography, WS-CDL, is an interactive description from global view which lacks formal semantics. The formal syntax and semantics, Process Algebra for WS-CDL (PA4WS), are proposed to describe WS-CDL using service channel and session channel. Particularly, The notation of WorkUnit is a reusable principle which plays an important role in WS-CDL. The WorkUnit of WS-CDL is modeled in PA4WS. To model the composition of WS-CDL, the patterns of WS-CDL interaction including interaction based information alignment (IBIA) and asynchronous interactions are depicted. The benefits of PA4WS are exemplified by the snippets of WS-CDL and their descriptions of PA4WS.
