4.2.2 LOGICAL MODEL OF INFORMATION IN AN OPEN ARCHIVAL INFORMATION SYSTEM (OAIS)
The previous subsection defines the types of Information Objects that are needed by an OAIS to enable the Long Term Preservation of information and effective access to the preserved information by the Designated Community. This subsection uses those Information Object descriptions to model the conceptual information structures required to accomplish these functions. The models presented in this subsection are not intended to imply an implementation, but rather to highlight the relationship among the types of information needed in the archival process.
