Caspa Preservabl Infrastructure Luigi Briguglio

  1. 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. 2. Presentation Planning • Preservable Infrastructure • CASPAR Infrastructure • Preservation Issues… • …and CASPAR Solutions • Development Process
  3. 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. 4. Preservable Equation Pure Service-oriented design • No Dependencies guarantees that the component can • Loosely coupled provide functionality without requiring • Distributed Self-Contained + cooperation of other components Component analysis, design and • Sharing know-how know- Well Described + development process is strongly based • Open Specification on complete – shared – open • Open Source documentation at any level • Open Documentation Adaptable + Design choices and implementation allows • Flexibility to adapt and configure each component to • Scalability Replaceable = provide always at least a minimal set of functionality independently from the deployment framework and condition Preservable Design choices and implementation allows • Interoperability to replace any component in the framework • Mantainability with compliant one.
  5. 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. 6. CASPAR & OAIS Info Model Information Descriptive Primary focus of Package Information archival preservation Needed for discovery Preservation Needed for long-term Content Description preservation Information Information Designated Community Knowledge Base interpreted Data interpreted using using Representation Object Information
  7. 7. Knowledge Preservation …just a “sequence of symbols”… but… Ancient Heroglyphic Egyptian Demotic Egyptian Greek Learning from the past (196 BC)
  8. 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”…
  9. 9. Digital World INGEST STORAGE ACCESS TIME ACCESS-Future
  10. 10. CASPAR & OAIS Func Model DATA Mngt PLANNING Producer Consumer INGEST ACCESS ADMINISTRATION STORAGE Manager
  11. 11. CASPAR BROCHURE CASPAR MAIN QUESTION
  12. 12. Preservation Issues 1… 1. How To guarantee a digital information may be accessed and understood in the future 2. How To guarantee a proper information package management within and OAIS Archive 3. How To guarantee long-time preservation maintenance of any information package
  13. 13. Preservation Issues 2… 4. How To guarantee retrieval of Archival Information 5. How To guarantee intellegibility within heterogeneous Designated Communities and their digital information 6. How To guarantee preservation actors are informed about change events
  14. 14. Preservation Issues 3… 7. How To guarantee an adequate security access with the proper rights to any resource and functionality within an OAIS Archive 8. How To guarantee an adequate integrity and identity for any Archival Information

  22. 22. Answer - 1 • To guarantee a digital information may be accessed and understood in the future, you need an adequate OAIS Representation Information REPINFO REG RepInfo ToolBox VIRT Registry Virtualisation
  23. 23. Answer - 2 • To guarantee a proper information package management within and OAIS Archive, you need to create an adequate OAIS Information Package PACK Packaging
  24. 24. Answer - 3 • To guarantee long-time preservation maintenance of any information package, you need an implementation of OAIS Archival Storage PDS Preservation DataStores
  25. 25. Answer - 4 • To guarantee retrieval of Archival Information, you need an OAIS Finding Aids FIND Finding
  26. 26. Answer - 5 • To guarantee intellegibility within heterogeneous Designated Communities and their digital information, you need to manage Designated Community Profiles and their Knowledge Base KM Knowledge
  27. 27. Answer - 6 • To guarantee preservation actors are informed about change events, you need events an adequate management of message exchange POM Orchestration
  28. 28. Answer - 7 • To guarantee an adequate security access with the proper rights to any resource and functionality within an OAIS Archive, you need a Security and DRM Management DAMS DRM Data Access Manager Digital Rights Manager & Security
  29. 29. Answer - 8 • To guarantee an adequate integrity and identity for any Archival Information, you need an Authenticity Tool AUTH Authenticity
