| Summary: | The activity of the Ph.D. student Juri Luca De Coi involved the research field of policy languages and can be divided in three parts.
The first part of the Ph.D. work investigated the state of the art in policy languages, ending up with:
(i) identifying the requirements up-to-date policy languages have to fulfill;
(ii) defining a policy language able to fulfill such requirements (namely, the Protune policy language); and
(iii) implementing an infrastructure able to enforce policies expressed in the Protune policy language.
The second part of the Ph.D. work focused on simplifying the activity of defining policies and ended up with:
(i) identifying a subset of the controlled natural language ACE to express Protune policies;
(ii) implementing a mapping between ACE policies and Protune policies; and
(iii) adapting the ACE Editor to guide users step by step when defining ACE policies.
The third part of the Ph.D. work tested the feasibility of the chosen approach by applying it to meaningful real-world problems, among which:
(i) development of a security layer on top of RDF stores; and
(ii) efficient policy-aware access to metadata stores.
The research activity has been performed in tight collaboration with the Leibniz Universität Hannover and further European partners within the projects REWERSE, TENCompetence and OKKAM.
