PREMIS in DOMS
The PREMIS preservation metadata as defined in the PREMIS Data Dictionary is "the information a repository uses to support the digital preservation process." One of the main principles behind PREMIS is that you need to be very clear about what you are describing. PREMIS defines five kind of entities: Intellectual, Objects, Events, Agents and Rights. This is called the PREMIS data model: [indsæt figur]
1. Intellectual entities are conceptual and might be called "bibliographic entities".
2. Object entities are what are actually stores and managed in the preservation repository
3. Event entities aggregate information about actions that affect objects in the repository
4. Agent entities are actors that have roles in events and in rights statements
5. Rights entities aggregate information about rights and permissionsthat are directly relevant to preserving objects in the repository.
