Language design of creating compound metadata schama method "fuzzy schema" based on museum information

As information technology has progressed recently, the amount of contents that can be used increase. And, there is an enviroment in which lots of contents can be accessed at anytime and anywhere. In this situation, a technology is needed to extract useful information from various contents by using metadata in order to meet the requirements. In this paper, we summarize the current state of metadata. technology and problems. Based on it, we propose the concept called Fuzzy Schema. Fuzzy Schema can flexibly construct metadata schema if necessary. And we also describe the design of Fuzzy Schema language taking an example of metadata schema of museum.
