Archival Information Unit (AIU)[edit]
"An Archival Information Package whose Content Information is not further broken down into other Content Information components, each of which has its own complete Preservation Description Information. It can be viewed as an ‘atomic’ AIP. An example of an AIU would be a table of numbers representing temperatures in a certain region with all the associated documentation describing how and where the temperatures were measured, what instruments were used to make the measurements, who made the measurements, why they were made, what processing has been performed on the measurements and who has had custody of these measurements since they were first created, how the measurements relate to other information, how the measurements can be uniquely referenced by others, etc." (OAIS, p.1-8, Section 1.7.2)
