Abstract
Recently digital technology has been developing very rapidly. Efforts have been concentrated on computer-, internet-, and database-technology. The Internet infrastructures based on the broad band have just been established last year and, in the near future, they are expected to be more stable and advanced to higher levels. For several years, Kosaido Co., Ltd. has been developing a variety of technology and contents productions concerned with the digital archive of cultural heritage and its applications. In this paper we describe our concept and some examples of our products. We anticipate that advances in digital technology will greatly improve the relevant media.
