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 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

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 Content Information Data Object interpreted using interpreted using Designated Community Knowledge Base Information Package Preservation Description Information Needed for long-term preservation Descriptive Information Needed for discovery Primary focus of archival preservation Representation Information

7 Knowledge Preservation …just a sequence of symbols… but… Ancient Heroglyphic Egyptian Demotic Egyptian Greek 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 its a sequence of symbols…

18 CASPAR Facade Layer - 2 Information Access 1.Search Content Information 2.Obtain Information Packages and relative Contents and Descriptions OAIS Ingest Data Management Archival Storage Preservation Planning Administration Access

19 CASPAR Facade Layer - 3 Designated Community and Knowledge Management 1.Deal with Designated Community Profile and its own Knowledge Base 2.Identify and Provide Knowledge Gap for understanding a Content Information OAIS Ingest Data Management Archival Storage Preservation Planning Administration Access

20 CASPAR Facade Layer - 4 Communication Management 1.Notify and Alert for Change Event impacting long term preservation 2.Trigger Preservation Process OAIS Ingest Data Management Archival Storage Preservation Planning Administration Access

21 CASPAR Facade Layer - 5 Security Management 1.Deal with User Account, Role and Profile 2.Deal with Content Access Permissions 3.Deal with Digital Rights 4.Guarantee Authenticity OAIS Ingest Data Management Archival Storage Preservation Planning Administration Access

22 Answer - 1 accessed and understoodTo guarantee a digital information may be accessed and understood in the future, you need an adequate OAIS Representation Information REPINFO RepInfo ToolBox VIRT Virtualisation REG Registry

23 Answer - 2 information package managementTo guarantee a proper information package management within and OAIS Archive, you need to create an adequate OAIS Information Package PACK Packaging

24 Answer - 3 long-time preservation maintenanceTo guarantee long-time preservation maintenance of any information package, you need an implementation of OAIS Archival Storage PDS Preservation DataStores

25 Answer - 4 retrievalTo guarantee retrieval of Archival Information, you need an OAIS Finding Aids FIND Finding

26 Answer - 5 intellegibilityTo guarantee intellegibility within heterogeneous Designated Communities and their digital information, you need to manage Designated Community Profiles and their Knowledge Base KM Knowledge

27 Answer - 6 informed about change eventsTo guarantee preservation actors are informed about change events, you need an adequate management of message exchange POM Orchestration

28 Answer - 7 security access rightsTo 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 Data Access Manager & Security DRM Digital Rights Manager

29 Answer - 8 integrity and identityTo guarantee an adequate integrity and identity for any Archival Information, you need an Authenticity Tool AUTH Authenticity
