Definition
A set of information, incorporated by a person or system, that allows that person or system to understand received information. Since a key purpose of an OAIS is to preserve information for a Designated Community, the OAIS must understand the Knowledge Base the knowledge base of its Designated Community designated community to understand the minimum Representation Information representation information that must be maintained. The OAIS should then make a decision between maintaining the minimum Representation Information representation information needed for its Designated Communitydesignated community, or maintaining a larger amount of Representation Information representation information that may allow understanding by a larger Consumer consumer community with a less specialized Knowledge Baseknowledge base. This would be the equivalent of extending the definition of the Designated Communitydesignated community.
