A distributed material database system named Data-Free-Way (DFW) has been developed under the collaboration with four organizations which are National Research Institute for Metals (NRIM), Japan Atomic Energy Research Institute (JAERI), Power Reactor and Nuclear Fuel Development Corporation (PNC) and Japan Science and Technology Corporation (JST). The databases are built on the WWW sites of all four organizations and connected each other through the Internet. In addition, some other databases are developed to supplement DFW system by each organization with making the best use of their own advantage. The progress of system development is reported.
