Abstract

With the increasing acceptability of interoperability standards like Open Archives Initiative protocol for metadata harvesting, it is becoming feasible to build federated discovery services which aggregate metadata from different digital libraries (data providers) and provide a unified search interface to users. Content-based access control is one of the primary requirements of data providers. While this concept has been predominant in the research realm, practical systems incorporating this concept are rare. In this paper, we propose a framework that supports and enforces content-based access policies using existing COTS components. We have prototyped the framework by building a system using XACML, and a XACML policy engine. The system can also be generalized to environments other than digital libraries.
