SPA Specifications

Videos

Original videos may be analog, physical objects or born digital. All these archival masters are converted into preservation copies and usually also dissemenation copies. All of them are instantiations of a single record. If a carrier like a video tape contains several works, each of them is described as a rico:RecordPart to allow connections of separate instantiations.

Videos are described from three perspectives and by using three ontologies:

  • as archival entities with RiC
  • as digital objects with PREMIS
  • and as videos with EBUCore

Therefore, they always two class types:

  • Videos tapes and films are at the same time a rico:Instantiation and a ebucore:MediaResource.
  • Digital videos are rico:Instantiation/premis:Representation plus one or more premis:File/ebucore:MediaResource.

Videos are also described as objects.

PREMIS and EBUCore properties

The implemenation of PREMIS is limited to only a few classes and property and might be extended later.

Analog videos and video files are both defined as a ebucore:MediaResource and use respective properties.
