Research on the Theory of E-Government Emergency Information Publication Rapidly Based On Hierarchical Workflow

This paper studied the theory and technology about emergence information published rapidly,and defined the connotation and extension of emergence information published rapidly.Then the authors put forward a layered concept model for workflow and a hierarchical descriptive model of XML metadata,and upon which established a mechanism for workflow assembly and execution navigated by XML metadata,improved self-adjustability of the emergence information published system,and by the time decomposed complexity and reduced abstruseness of the problem related.
