Contextual Data Exchange

In this project we present the reusable data structure that addresses the issues of static, inflexible and practically non-interoperable authorization definitions. We first establish the structure that introduces enhanced expressivity, context-sensitivity and adaptability in descriptions of authorization constraints. We then develop the supporting software component and the web-based interface for definition and inspection of access authorizations established using the proposed structure. Based on that, we present a demonstration prototype and describe the application of the proposed structure both in terms of emerging solutions and existing authorization frameworks
