Workflow Enactor
The Workflow Management Coalition (WFMC, www.wfmc.org) defines a workflow as "The automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant to another for action, according to a set of procedural rules". In other words a workflow consists of all the steps and the orchestration of a set of activities that should be executed in order to deliver an output or achieve a larger and sophisticated goal. In essence a workflow can be abstracted as a composite service, i.e. a service that is composed by other services that are orchestrated in order to perform some higher level functionality.
Each workflow is deployed as a "higher order" composite service and the Workflow Enactor is the Grid enabled component responsible for the invocation, monitoring, and management of running workflows. The standard workflow description language WS-BPEL (www.oasis-open.org/committees/tc_home.php) has been selected as the workflow description format and being a standard it enables the separation of the workflow editing environment from the workflow enactor and facilitates their communication and integration.
