PREMIS is a metadata schema that is used for creating preservation metadata for digital objects. Preservation metadata for digital objects is crucial because it increases the likelihood of long term accessibility.
Examples of PREMIS can be found here
BGSU has yet to implement PREMIS but plans to in the near future. Below are the recommended core fields for BGSU PREMIS users:
1. Size: The size in bytes of the file or bitstream stored in the repository.
2. Format Designation: An identification of the format of the object.
3. OriginalName: The name of the object as submitted to or harvested by the repository, before any renaming by the repository.
4. StorageMedium: The physical medium on which the object is stored.
5. Restriction: A condition or limitation on the act.
The following is a list of core PREMIS fields recommended by the Library of Congress:
1. objectIdentifierType: A designation of the domain within which the object identifier is unique.
Example: OCLC Object Identifier
___________________________________________________
2. objectIdentifierValue: The value of the objectIdentifier
Example: 9605, UA396
___________________________________________________
3. objectCategory: The category of object to which the metadata applies.
Example: representation, file, bitstream
___________________________________________________
4. preservationLevelValue: A value indicating the set of preservation functions expected to be applied to the object.
Example: store
___________________________________________________
5. compositionLevel: An indication of whether the object is subject to one or more processes of decoding or unbundling.
Example: A may be compressed to create file B, which encrypted to create file C. A composition level of zero indicates the object is a base object and not subject to further decoding.
