14. 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 15AE9513 15ae9513.abc 15  9513  ?
