Lay Summary (English)

Lay summary
A large portion of the audio-visual heritage of our time is already storedon digital media or will be transferred in the near future onto suchmedia. The reasons are twofold: a) access to digital data - be it on localintranet or on the global internet - is very easy and efficient and b) agood deal of the audio-visual which is stored on analogue media (, video etc.) has to be transferred to new media because theold media is decaying by aging processes which, on the long term, willlead to a total loss of this part of the cultural heritage.However, the longterm archival of digital data is also still an unresolvedissue.The goal of this project is to develop and establish an archival systemfor digital data with focus on long-term archival as required by archivesand museums which preserve the audio-visual heritage of our time. Thefundamental idea is that institutions with long-term archival needs ofdigital data collaborate in order to build a geographically distributed,Internet based archival system. It has been of primary concern indesigning this system to minimizing the risk of data loss due to acatastrophic event (on a local or even regional scale such as adevastating earthquake) or false manipulation. In addition the archivalnetwork has to cope with the rapidly changing standards of informationtechnology and preserve readability of the data beyond changes of softwareand hardware technology.The archival network will be implemented as a distributed, self-organizingand optimized peer-to-peer (P2P) network with a high redundancy, based onan open protocol using XML technology. The data to be archived will bedistributed in redundant copies among all participants parties. It will beassumed that the data will be transported over untrusted channels andstored on untrusted nodes. Therefore, strong cryptography may be used toguarantee the integrity and privacy of the archived digital assets.
