4.3 INFORMATION PACKAGE TRANSFORMATIONS

The previous portions of this section have discussed the functional architecture of an OAIS and an information architecture to represent the Information Packages and associated Package Descriptions and Packaging Information. This subsection looks at the transformations, both logical and physical, of the Information Package and its associated objects as they follow a lifecycle from the Producer to the OAIS, and from the OAIS to the Consumer.

Figure 4-26 presents a high-level data flow diagram that depicts the principle data flows involved in OAIS operations. These flows do not include administrative flows such as accounting and billing.
