Abstract

This paper proposes using metadata in a Resource Description Framework (RDF) database for version management and access control. The proposed mechanism attaches metadata containing the version and access control information to an RDF statement. When new data (RDF statements) are derived based on the rules, the metadata are added to the new data. When a query is made to the RDF database, it is rewritten so that the metadata are considered. In addition, the mechanism is intended to be used on top of existing RDF database software for easy portability. An application of the proposed mechanism is shown in the context of the construction of a topic database for the conversation support of people with language disorders.
