CASPAR Preservable Infrastructure Addressing Preservation with an OAIS based Infrastructure Luigi Briguglio Engineering R&D Laboratory – Rome (Italy) 3rd Annual WePreserve Conference in Nice (France)

Presentation Planning Preservable Infrastructure CASPAR Infrastructure Preservation Issues… …and CASPAR Solutions Development Process

Preservable Architecture Usually Traditional framework has something called component/service which provides functionality, if and only if component is composed with other ones (required components/dependencies) Each CASPAR Key Component has to provide always at least a minimal set of functionality independently from the environment conditions.

Preservable Equation Self-Contained + Well Described + Adaptable + Replaceable = Preservable Pure Service-oriented design guarantees that the component can provide functionality without requiring cooperation of other components Component analysis, design and development process is strongly based on complete – shared – open documentation at any level No Dependencies No Dependencies Loosely coupled Loosely coupled Distributed Distributed Sharing know-how Open Specification Open Specification Open Source Open Source Open Documentation Open Documentation Design choices and implementation allows to adapt and configure each component to provide always at least a minimal set of functionality independently from the deployment framework and condition Flexibility Flexibility Scalability Scalability Design choices and implementation allows to replace any component in the framework with compliant one. Interoperability Interoperability Mantainability Mantainability

CASPAR Infrastructure CASPAR Foundation Team has defined and implemented an Infrastructure by adopting the OAIS Reference Model (ISO:14721:2003) CASPAR Infrastructure is SOA-based
