HOW TO TRANSFER RELATION-BASED WORKFLOW MODEL TO STANDARD XPDL MODEL

As relation-based workflow modeling tool lacks an interface with standard workflow process definition language (XPDL),established by Workflow Management Coalition (WFMC),it is very difficult for the process model designed by the modeling tool to be transferred to other like products.Aiming at the solution of this problem,this paper gives an introduction to the mapping relation of the relational database with XPDL and,meanwhile,puts forward the idea of making data transition between them.Finally,the visual format transition tool,making use of XML and DOM techniques,is used and the transition is achieved.Results of transition are given.
