Workflow Modeling with XML and Agent Federation

Aiming at realizing flexible and dynamic workflow management in the distributed environment,we organize the workflow management system as a possibly nested Agent federation,and define the workflow as a set of activities achieved by Agents federation cooperated with each other.Workflow process planning is carried out based on the collaborative intention of Agents to execute activities with joint efforts.Such an approach successfully merges the static workflow process decomposition with its dynamics running.Moreover,using XML as the workflow modeling language makes it more operable and extensible than traditional ways. This paper also introduces the workflow modeling environment and the steps to model a workflow process.
