Hoe duurzaam is JPEG2000?

Via Ingmar Koch werd ik geattendeerd op een artikel van Johan van der Knijff (KB), getiteld: JPEG 2000 for Long-term Preservation: JP2 as a Preservation Format.


Het in het engels gestelde artikel wordt als volgt samengevat:
Despite the increasing popularity of JPEG 2000 in the archival community, the suitability of the JP2 format for long-term preservation has been poorly addressed by existing literature. This paper demonstrates how some parts of the JP2 file specification (related to ICC profiles and grid resolution) contain ambiguous information, leading to a situation where different software vendors are interpreting the standard in slightly different ways. This results in a number of risks for preservation. These risks could be reduced by applying some minor changes to the format specification, in combination with the adherence to the updated standard by software vendors.
