Web-Based Policy Interoperability via a Semantic Policy Interlingua

Abstract

In this project, we investigated the problem of secure information exchange and integration across organization/domain boundaries using policy management. We developed a query federation test-bed that allows users to make queries against multiple Semantic Web datasets simultaneously. This system performs on-the-fly mash-ups of sensitive data, the access to which needs to be regulated. It also supports multi-schema federation, which allows users to make queries in their schema without worrying about the schemas of the datasets in the federation. We also studied policy languages such as XACML and AIR and modeled them in W3C's Rule Interchange Format (RIF) to enable dynamic translation between policies in these commonly used policies. Lastly, we studied how secure information sharing would benefit public education using Massachusetts as a usecase.
