PREMIS Workshop at iPres 2014Implementation at The Royal Library of DenmarkSlide 3 Currently at the Royal Library Goal Preserve data independent of repository technology This means: At any time, repository software can be exchange Loss of Repository does not mean loss of preserved data

PREMIS Workshop at iPres 2014Implementation at The Royal Library of DenmarkSlide 14 Reasons for id. requirements 1. Leave it 100% to the bit preservation solution ◦ Risk since it is crucial information in preservation – outsource of responsibility ◦ Eliminate possible optimisation of packaging more files or files and metadata in the same packages 2. Naming files with the identifier ◦ file name is not part of the file itself ◦ restrictions to how files are named ◦ may not make same sense in the future 3. Put identifier into files as inherited metadata ◦ would need to change original bits ◦ knowledge of how to extract identifiers from file formats 4. Wrap files and identifier in a package format ◦ requirements for the abilities of the package format put the id. with the file 15AE ae9513.abc 15  9513  ?
