We have brought forward a new workflow model - extended xinpai - drived workflow computing model based on xinpai - drived workflow computing model , integrated with the workflow standard semantic model described by workflow process definition language ( wpdl ) and established by workflow management coalition ( wfmc ) . then we developed a j2ee based workflow management system prototype - j2ee - wfms basing on that model 我們在繼承信牌驅(qū)動式工作流計算模型的基礎(chǔ)上,結(jié)合工作流管理聯(lián)盟( wfmc )所制定的用工作流過程定義語言( wpdl )描述的工作流標(biāo)準(zhǔn)語義模型,又提出了一個新的工作流模型? ?擴(kuò)展的信牌驅(qū)動式工作流計算模型。
