Recent materials data systems require flexible data modeling and data evaluation modules for the retrieved data. More than ten years ago, an inventory of such materials data evaluation modules has been collected by the international collaboration of the VAMAS TWA 10. The concept of the markup language for materials data (MatML) has been published, but the examples of actual implementation of materials data and related numerical evaluation/analysis are very limited. This work is to demonstrate the procedures of database building with the MatDB developed by the New Materials Center in Japan, as an extension of the original MatML developed in the US. We use the numerical data of creep-rupture from the NIMS Creep Data Sheet, and develop the software modules for analytical modeling of the data using the time-temperature parameters (TTP). With the implementation of Mat-DB and data evaluation modules that run under the browser we can have an interoperable materials data system.
