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

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?”
![Page 13: 1 The CASPAR Project Key Components - Overview Luigi Briguglio Engineering R&D Laboratory – Roma CASPAR FINAL WORKSHOP IN ROME SCUOLA SUPERIORE PUBBLICA](https://reader036.vdocument.in/reader036/viewer/2022062417/5514b8aa550346f06e8b65bb/html5/thumbnails/13.jpg)
13CASPAR FINAL WORKSHOP IN ROME
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.
![Page 14: 1 The CASPAR Project Key Components - Overview Luigi Briguglio Engineering R&D Laboratory – Roma CASPAR FINAL WORKSHOP IN ROME SCUOLA SUPERIORE PUBBLICA](https://reader036.vdocument.in/reader036/viewer/2022062417/5514b8aa550346f06e8b65bb/html5/thumbnails/14.jpg)

17CASPAR FINAL WORKSHOP IN ROME
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…
![Page 18: 1 The CASPAR Project Key Components - Overview Luigi Briguglio Engineering R&D Laboratory – Roma CASPAR FINAL WORKSHOP IN ROME SCUOLA SUPERIORE PUBBLICA](https://reader036.vdocument.in/reader036/viewer/2022062417/5514b8aa550346f06e8b65bb/html5/thumbnails/18.jpg)
18CASPAR FINAL WORKSHOP IN ROME
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.

23CASPAR FINAL WORKSHOP IN ROME
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
![Page 24: 1 The CASPAR Project Key Components - Overview Luigi Briguglio Engineering R&D Laboratory – Roma CASPAR FINAL WORKSHOP IN ROME SCUOLA SUPERIORE PUBBLICA](https://reader036.vdocument.in/reader036/viewer/2022062417/5514b8aa550346f06e8b65bb/html5/thumbnails/24.jpg)
24CASPAR FINAL WORKSHOP IN ROME
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.
