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 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
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

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