چکیده

Social applications are one of the fastest growing areas in the Web. However, privacy issues ensue if all information of all users of these applications is stored on a single computer system. With small extensions to Semantic Web technologies and Linked Data concepts, a distributed approach to the social web is possible, where users retain fine-grained control over their data and are still able to combine their data with users on different systems. We describe our concept of a Policy-enabled Linked Data Server (PeLDS) obeying user-defined access policies for the stored information. PeLDS also supports configurationfree distributed authentication. Access policies are expressed in a newly developed compact notation for the Semantic Web Rule Language. Authentication is performed using SSL certificates and the FOAF+SSL verification approach. We evaluate our concept using a prototype implementation and a distributed address book application.
