Material database can play an important roll in engineering fields, such as material science, mechanical engineering and civil engineering. Many material databases were built, however, each database has its own database format. XML (eXtensible Markup Language) is very useful and strong language to describe database and define the structure using DTD, XML Schema, Relax, etc. Therefore, database definition by XML is suitable for a template of databases having different formats. The research project about the XML material database on commission of NIMS has been progressed from 1997 to discuss interpretation and interoperability of the databases, establish the basic format of the database and build new fact database about amorphous materials. In this paper, we (XML database WG of the project) show the result of the project about design concept of the basic database structure and show the comparison with MatML developed by NIST.
