''We have decided not to use PREMIS in DOMS, at least when it comes to audio files we have digitized via the Quadriga system. That is due to the fact that all the needed technical metadata are automatically generated or manually written in the Quadriga system. And those metadata will be exported to DOMS together with the audio file.''

''Below are the investigations we made in order to find out which components from PREMIS we would use for digital resources without automatically generated technical metadata'' 

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.

 * '''1. Intellectual entities''' are conceptual and might be called "bibliographic entities".
 * '''2. Object entities''' are what are actually stored 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.

We have chosen to use only the entity '''Object (or Digital Object)'''. Below is an outline of the semantic units and components we are going to adopt:
 
 * 1.1 objectIdentifier (M, R)
 * 1.1.1 objectIdentifierType (M, NR)
