An agent-based linked data integration system

With the advent of the Web of Linked Data, new challenges to federated query processing are emerging. Different from traditional federated database systems which do static data integration, this Web of Data is open and ever-changing. In this paper, we present a agent-based architecture providing a flexible and decoupled solution for the federated queries over Linked Data. Based on the presented architecture, a Linked Data Management System (LDMS) has been developed. LDMS manages Linked Data in a virtual way, i.e., it does not load remote data into a local data store. With an application scenario, we demonstrate the scalability and extensibility of the presented architecture.
