ABSTRACT:
A method of executing and controlling a workflow process includes a request-response control process for coordinating activities between a plurality of entities, whereby an entity creates and sends a message requesting execution of an activity and another entity receives, parses and responds to the request. The message includes activity-specific data and activity status data. The activity status data signifies, for example, whether a corresponding activity has been successfully performed (i.e., completed) or failed. Process information, including control logic for the workflow process, is specified in an at least one uncompiled document, which may include an extensible stylesheet and an extensible markup language document. A document type definition defines the structure of the document. The control logic may include serial, AND-parallel, OR-parallel, XOR-parallel, CON-parallel and iterative instructions and a definition of successful completion and/or failure for an activity according to the control logic. The control logic also specifies a forward transition for a completed activity and a backward transition for a failed activity. A parser processes the message according to the control logic for the workflow process and the document type definition. A compiled workflow engine and database are not required.
