Proposal for a semantic data categorization system through reusing metadata

At present, there are many data on vast Web. From the activities of Semantic Web, some data have had their semantics as metadata. But it can be hardly said that current Web is comfortable and convenient. Today's the amount of metadata on Web is not enough to take advantage of it. Consequently, we proposed a simple model and thumbnail syntax of metadata. Additionally, we set out data categorization system with utilizing relationship of metadata, and confirmed that our proposed metadata is useful and suitable for practical use.
