| Semantic unit | 1.3.1 preservationLevelType |
|---|
| Definition | A value indicating the type of preservation functions expected to be applied to the Object for this preservation level. |
| Applicability | Intellectual Entity / Representation, File |
| Obligation | Optional |
| Repeatability | Not repeatable |
| Rationale | Digital preservation functionality can be typed to express various aspects of the preservation. For instance bit-safety can represent a preservation level type, where values of this type can be used to express degree of replication and independence between copies. Likewise logical preservation can represent a type, where values of this type express whether functional preservation is done via format migration, emulation etc. |
| Data constraint | Value should be taken from a controlled vocabulary. |
| Creation /
Maintenance notes | The preservationLevelType may be assigned by the repository or requested by the depositor and submitted as metadata. |
| Usage notes | Only one preservationLevelType may be recorded per preservationLevel container. If a further preservationLevelType applies to the Object in a different context, a separate preservationLevel container should be repeated. |
| Examples | Bit preservation Logical/functional preservation Bit preservation Logical/functional preservation |
