Abstract :
From the analysis of workflow instance relevant data (WIRD), and a modeling method of WIRD based on object Petri nets is proposed. The method dynamically constructs an access mechanism of WIRD, to guarantee the security of WIRD. Moreover, a version management mechanism of WIRD is adopted as well as a collaborative communication mechanism of concurrent tasks is established to solve the inconsistency of WIRD during execution of workflow. The research of applied example has shown that this modeling method is significant in the application of access right and integrality of WIRD
