3rd Annual WePreserve Conference Nice 2008

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
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. 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
