The CASPAR Project • The CASPAR project is mainly based on standard ISO:14721:2003 OAIS • In this perspective, its Architecture is defined for • Managing key concepts of the OAIS reference model • Supporting main functionality identified in the OAIS functional model • Moreover, the CASPAR project aims to define, and implement, interfaces and functionally independent components
Designated Community Knowledge Base CASPAR & OAIS Info Model Descriptive Information Information Package Primary focus of archival preservation Needed for discovery Preservation Description Information Needed for long-term preservation Content Information interpreted using Data Object interpreted using Representation Information
Consumer Producer Manager CASPAR & OAIS Func Model
OAIS Mandatory Responsability • Negotiation and Acceptance of submitted information • Provide Long-Term Preservation Information • Determine Designated Community • Information preserved is Independently Understandable to the Designated Community • Follow documented policies and procedures which ensure that the information is preserved against all reasonable contingencies • Make the preserved information available to the Designated Community.

Preservation Issues 1… • How To guarantee a digital information may be accessed and understood in the future • How To guarantee a proper information package management within and OAIS Archive • How To guarantee long-time preservation maintenance of any information package • How To guarantee retrieval of Archival Information
Preservation Issues 2… • How To guarantee intellegibility within heterogeneous Designated Communities and their digital information • How To guarantee preservation actors are informed about change events • How To guarantee an adequate security access with the proper rights to any resource and functionality within an OAIS Archive • How To guarantee an adequate integrity and identity for any Archival Information

The Big Question “What do I have to do for preserving my digital content object, and guarantee it could be used and understood in the future?”
Step 1 • First of all, preserving a digital content object means that • The digital content object has to be “prepared” and “packed” in a proper way to be “ingested” in the digital archive system that will manage and maintain it for a long time. • During the preparation, a package containing digital content object and all the necessary information is created. • And then that package is stored.
CASPAR Ingestion Information Package Management • Ingest Content Information • Create Information Package • Representation Info • Descriptive Info • Preservation Description Info • Check Information Package • Store Information Package for long term OAIS Preservation Planning Ingest Data Management Access Archival Storage Administration
Step 2 • After the ingestion, the digital content information may be available for using and understanding it. • In this case, the internal package of the digital archive system has to provide a “usable and understandable” information to the consumer which requests it. • And so…
Step 2 • And so… • The digital content object has to be “found” within the digital archive, through its descriptive information and “checked” for any restricting access right policy. • After that, processed information is “prepared” and “packed” in a proper way to be “accessed” from the digital archive system and made available for its intellegibilty at the consumer, taking into account the consumer knowledge profile.

CASPAR Designated Community Designated Community and Knowledge Management • Deal with Designated Community Profile and its own Knowledge Base • Identify and Provide Knowledge Gap for understanding a Content Information OAIS Preservation Planning Ingest Data Management Access Archival Storage Administration
Step 3 • Ingestion and Access represent the only two activities which involve producer and consumer of the digital content object and allow their interaction with the digital archive system. • Neither Ingestion and Access characterise the digital archive system as a “long term preservation system”. • What, instead, extends the usual digital archive systems and promotes them as “preservers” is the third activity
Step 3 • The digital content object within the digital archive needs to be maintained in order to be accessed, used and understood for whatever changes during its long-term lifecycle. • And that implies that any impacting change in the real world needs to be identified and notified to the responsible of preservation in order to take into account the proper corrective actions, according to defined preservation plans.
