Abstract: Resource Description Framework (RDF) and RDF
Schema (collectively called RDF(S)) are the normative language to describe the
Web resource information. With the massive growth of RDF(S) information, how to
effectively store them is becoming an important research issue. By analysing
the characteristics of RDF(S) data and schema semantic information in depth,
this paper proposes a multiple storage model of RDF(S) based on relational
databases. An overall storage framework, some detailed storage rules, a storage
algorithm and a storage example are proposed. Also, the correctness of the
storage approach is discussed and proved. Based on the proposed storage
approach, a prototype storage tool is implemented, and experiments show that
the approach and the tool are feasible.
Keywords: RDF, RDF schema, relational database, storage.
