6. Approach:
Dealing with Knowledge Base
• According to OAIS:
– “Data about data” are distinguished to various categories.
– One very important is that of Representation Information
(RepInfo)
– RepInfo allows interpretation of data object
– Interpretation is depending from the “Community” and its own KB
• Knowledge Base of Designated Community
– Each actor or community can be characterized by a profile that
contains those RI modules that are assumed to be
available/known.
– Those RI modules allow interpretation of digital objects

7. Approach:

Preservation is a “Process”
and it’s important to monitor
and notify about “event
