title: Policy-Driven Repository Interoperability:  Enabling Integration Patterns for iRODS and Fedora

abstract: Given the growing need for cross-repository integration
  to enable a trusted, scalable, open and distributed
  content infrastructure, this paper introduces the Policy-
  Driven Repository Interoperability (PoDRI) project
  investigating interoperability mechanisms between
  repositories at the policy level. Simply moving digital
  content from one repository to another may not capture
  the essential management policies needed to ensure its
  integrity and authenticity. Platform-independent, policyaware
  object models, including policy expressions, and
  a distributed architecture for policy-driven management
  are fundamental building blocks of a sustainable access
  and preservation infrastructure. This project integrates
  iRODS and Fedora to demonstrate such an
  infrastructure. Using iRODS and its rules engine,
  combined with Fedora’s rich semantic object model for
  digital objects, provides the basis for implementing a
  policy-driven test-bed. Using a policy-driven
  architecture is an essential part of realizing a fully
  model-driven repository infrastructure capable of
  decoupling the permanent digital content from the
  constantly evolving information technology used to
  support them.
