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 designguarantees that the component can provide functionality without requiring cooperation of other components
Component analysis, design and development process is strongly based on complete – shared – opendocumentation at any level
•• No DependenciesNo Dependencies•• Loosely coupledLoosely coupled•• DistributedDistributed
• Sharing knowSharing know--howhow•• 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
