A Novel and Complete Approach for Storing RDF(S) in Relational Databases

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.
