| Semantic unit | 1.2 objectCategory |
|---|
| Definition | The category of object to which the metadata applies. |
| Obligation | Mandatory |
| Repeatability | Not repeatable |
| Rationale | Preservation repositories are likely to treat different categories of objects (Intellectual Entities, Representations, Files, and Bitstreams) differently in terms of metadata and data management functions, it is therefore important to differentiate between the categories. |
| Data constraint | Value should be taken from a controlled vocabulary. A controlled vocabulary is available at: |
| Controlled vocabulary | http://id.loc.gov/vocabulary/preservation/objectCategory.html  |
| Usage notes | A filestream should be considered a file. |
| Examples | intellectual entity representation file bitstream |
