GiN: a graphical language and tool for defining itask workflows

摘要: Workflow Management Systems (WFMSs) are software applications that coordinate business processes. The coordination is based on a workflow model, expressed in domain-specific Description Language (WDL). WDLs typically graphical languages because the specification has to be understandable for domain experts as well application developers. Commonly, only simple workflows can described while additional coding needed turn description into running application. iTask system combinator library, embedded Clean, construct WFMSs. Complex defined declaratively from which complete web-based generated. However, textual less suitable who used notations. In this paper we address problem and present GiN: notation workflows, prototype implementation of tool GiN interactively graphically. fully integrated system: it just another component, created with subsequently added executed dynamically part other workflows.
