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 DependenciesNo Dependencies• Loosely coupledLoosely coupled• DistributedDistributed
• Sharing know-howSharing know-how• Open SpecificationOpen Specification• Open Source Open Source • Open DocumentationOpen 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
• FlexibilityFlexibility• ScalabilityScalability
Design choices and implementation allows to replace any component in the framework with compliant one.
• InteroperabilityInteroperability• MantainabilityMantainability
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

We still cannot understand it
(the meaning has not been preserved)
We can only understand it’s a “sequence of symbols”…
