【Abstract】 The characteristics of some popular workflow definition languages were discussed first. On the basis of the characteristics of these workflow definition languages,a new workflow definition language named SWDL designed for a distributed transactional workflow management system ScopeWork was presented, and an example was given to demonstrate how to define a complex transactional workflow with SWDL. SWDL is compatible with the interface definition language of CORBA, supports the definitions of distributed workflow applications, and has the ability to model transactional workflows.更多还原
