Schema Design for Information Liaison between Local Governments and the Central Govenment

Under the auspieces of "E-Local Governments System Development Panel" (founded by Ministry of Internal Affairs and Communications), a workflow sytem and document management system for information liaison between the central government and local governments have been studied from 2004 to 2005. The document man- agement system adopts XML for representing documents and data. This paper focuses on schema design in this project, ecpecially factorization among the schemas for prefectures and those for local governments. The adoption of the "Garden of Eden" style and schema conversion tools allows such schema factorization.
