Embodiment Construction

[0020] In order to make the features and advantages of the present invention more clearly understood, below in conjunction with accompanying drawing, describe in detail as follows: figure 1 As shown, the architecture of the model conversion system of the present invention is described, where the direction of the arrow indicates the process of implementing the conversion method. When the active model file is imported into the conversion system, the specific conversion steps in this embodiment are:

[0021] 1) The XML file reader / writer reads the source model file into memory, and converts it into a source document memory structure based on XML grammar rules, that is, the xml form of the source model file;

[0022] 2) The XML-metamodel converter converts the XML-based memory structure obtained in step 1 into a metamodel-based memory structure, that is, the metamodel form of the source model file;

[0023] 3) The transformation engine converts the memory structure based on the m...

Abstract

The invention discloses a method for carrying out mutual conversion to the flow definition of workflow meeting the XML criterion based on a metamodel; the invention also relates to a system for realizing the method, which consists of four parts: a rule management module, a conversion engine, an XML read-write device and an XML-metamodel convertor; and the conversion of a workflow model is realized through building a mapped relation between metamodels embodied by XML. The method has universality, solves the conversion problems that the prior tool for flow conversion can only ensure two kinds of flow definition languages, and reduces the time and cost expenditure brought by developing the conversion tool repeatedly.

Description

technical field [0001] The invention relates to workflow process definition conversion technology, in particular to a metamodel-based method and system for conversion of workflow process definition expressed in XML syntax. Background technique [0002] Workflow technology is a rapidly developing technology and widely used in various industries. Its main feature is the automation of business processes. Workflow is a kind of business process that can be fully or partially automatically executed. It is transmitted and executed between different executors according to a series of process rules, documents, information or tasks. [0003] Regarding workflow process definition, there are many popular specifications, commonly used ones are: BPEL (Business Process Execution Language For Web Services) jointly launched by BEA, Microsoft and IBM, which provides an XML annotation and semantics for specifying based on Business process behavior of Web services; XPDL (XML Process Definition...
