  1. 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)

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

  3. 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.

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

  5. 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

  6. CASPAR & OAIS Info Model Designated Community Knowledge Base Descriptive Information Information Package Primary focus of archival preservation Needed for discovery Preservation Description Information Needed for long-term preservation Content Information interpreted using Data Object interpreted using Representation Information

  7. Knowledge Preservation Ancient Heroglyphic Egyptian Demotic Egyptian Greek …just a “sequence of symbols”… but… Learning from the past (196 BC)

  8. Phaistos disk (dated to 1700 BC) We still cannot understand it (the meaning has not been preserved) We can only understand it’s a “sequence of symbols”…

  12. Preservation Issues 1… • How To guarantee a digital information may be accessed and understood in the future • How To guarantee a proper information package management within and OAIS Archive • How To guarantee long-time preservation maintenance of any information package

  13. Preservation Issues 2… • How To guarantee retrieval of Archival Information • How To guarantee intellegibility within heterogeneous Designated Communities and their digital information • How To guarantee preservation actors are informed about change events

  14. Preservation Issues 3… • How To guarantee an adequate security access with the proper rights to any resource and functionality within an OAIS Archive • How To guarantee an adequate integrity and identity for any Archival Information
