T □: A Domain Specific Language for Rapid Workflow Development

Abstract

Abstract. In MDE, software systems are always synchronized with their models since changes are made first to the model whenever there are changes in the requirement specifications. While MDE has a lot of potential, it requires maturity and tool support. In this research we present a framework for a workflow management system based on the MDE approach. We propose a domain specific language, T (T-Square) for rapidly specifying details of (workflow) tasks and their associated user interfaces which may be used with the NOVA Workflow, an executable workflow management system. T includes syntax for writing procedural statements, for querying an ontology, for declaring user interfaces, for applying access control policy, and for scheduling tasks, using Xtext to write the grammar. We apply transformation methods, based on Xtend, to generate executable software from the abstract task specifications. A running example from health services delivery illustrates the usefulness of this approach.

Live process modeling with the BPMN Sketch Miner

“…However, unlike the BPMN Sketch Miner's textual DSL, the S-BPM is designed for explicitly declaring the whole model's structure textually. T-Square [55] is another declarative textual DSL for rapid processes description by specifying the tasks and the branching conditions. This DSL is incorporated in NOVA [43] which is an Eclipse-based editor which enables modeling workflows graphically based on the Compensable Workflow Modeling Language (CWML).…”
