Knowledge base
- Creighton Barrett
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 of its designated community to understand the minimum representation information that must be maintained. The OAIS should then make a decision between maintaining the minimum representation information needed for its designated community, or maintaining a larger amount of representation information that may allow understanding by a larger consumer community with a less specialized knowledge base. This would be the equivalent of extending the definition of the designated community.
