License for the Web of Data

Reasoning about rights and licenses in the Web of Data

Participant : Serena Villata.

In the domain of Linked Open Data a need is emerging for developing automated frameworks able to generate the licensing terms associated to data coming from heterogeneous distributed sources. Together with Guido Governatori (NICTA, Australia) and Antonino Rotolo (University of Bologna, Italy), Serena Villata proposed and evaluated a deontic logic semantics which allows to define the deontic components of the licenses, i.e., permissions, obligations, and prohibitions, and generate a composite license compliant with the licensing items of the composed different licenses. The approach is evaluated using the SPINdle defeasible reasoner, where the proposed heuristics have been hard coded in the reasoner. The prosecution of this research line has seen the analysis of the compatibility of a set of licensing terms (always using SPINdle), the analysis of the role of licenses associated to vocabularies, and the development of the Licentia suite of services to reason over licenses and help users to deal with such kind of information. The results of this research line have been published at the International Semantic Web Conference demo session [87] .
