| Semantic unit | 4.1.8 linkingObjectIdentifier |
|---|---|
| Definition | The identifier of an object associated with the Rights statement. |
| Obligation | Optional |
| Repeatability | Repeatable |
| Rationale | Rights statements must be associated with the objects to which they pertain, either by linking from the Rights statement to the object(s) or by linking from the object(s) to the Rights statement. This semantic unit provides the mechanism for the link from the Rights statement to an object. |
| Data constraint | Container |
| Usage notes | Linking semantic units are mandatory in the sense that a repository needs to know the information, but are defined as optional because PREMIS does not specify in which direction the linkage should be. In particular, linkingObjectIdentifier is optional because in some cases it will be more practical to link from the object(s) to the Rights statement; for example, a repository may have a single Rights statement covering thousands of public domain objects. |
