Abstract: Metadata, which has been known only among librarians and other professionals, has got to be diffused all over the "real" world. This change has caused by the World Wide Web. Ordinary citizens have come to generate reviews for products on e-commerce sites, and tags on photo sharing services with consciously. In this paper, I analyze the process of that metadata usage has been diffused, and discuss the way to adopt the situation where everybody utilize metadata everywhere in daily life.
