Digital Collaborative Authoring Platform On The Workflow Process Of Editing Tools, The Design And Realization

WorkFlow Technology has been a research hotspot of the application of computer science since the last century 90's. Thus it is so important to study the WorkFlow in depth that it would raise up the degree of informationization, the working efficiency and the market competitiveness of an enterprise.WorkFlow Editor is a very important part of a WorkFlow system, and it will improve the efficiency of the system greatly.A XPDL-based WorkFlow editor is very frequently used in 863 project:Media Network Platform for Large-scale Collaborative Creation. It is used to build model in projects such as games, cartoons, movies etc. There are several kinds of XPDL-based WorkFlow editor now. For example, JAWE, TWE, WFMOPEN, JAWFLOW etc. They work very well, but they are not web-based program, so they are not quite compatible with the Media Network Platform for Large-scale Collaborative Creation.This paper analyzed some Workflow systems and studied the WorkFlow standards, then designed and implemented a JsFlowEditor, which is mostly written in JavaScript, based on XPDL and MVC patterns, JsFlowEditor has a pure-web visual interface, supports the drag&drop operations, and is fully compatible with the Workflow definition standard of WfMC. It also can save the flow chart as a XPDL file, and it works well reversely. JsFlowEditor is validated and used in the 863 project--Media Network Platform for Large-scale Collaborative Creation. Considering the high degree of flexibility of its B/S architecture, it might be used in more WorkFlow systems.
