Abstract

In this paper, we describe a system for sharing distributed XML data among organizations using adjustable schema. In our system, each organization can adjust common DTD (Document Type Definition) within the bound of rule to create its own DTD, which is called adjusted DTD. And then it can describe information with tags according to the adjusted DTD. Basically, the upper structure of shared XML data is common. Adjusted DTDs are managed centrally by a server. The server also examines whether they conform to an adjusting rule. We discuss a result of prototype system using welfare information based on Web Services technology. In the prototype, we can register adjusted DTDs and search for them through Web browser.
