We are developingTsunami Digital Library(TDL) which consists of the documents of newspaper articles, reports and books, videos, and CGs on the tsunami occurred in the past, and are opened through Web.

The schemas of these documents depend on a kind of documents. Therefore,each document has a different schema. In order to make a traversal retrieval crossing whole documents, it is nec- essary to use a unified schema to integrate all schemas for XML documents. This paper describes the design of integration schema and retrieval system, and the system implementations. We can retrieves easily some requested data from TDL through
