Abstract
|
The report CODA FORM discusses three areas:
• Criteria for archive formats
• Evaluation of format registers
• Test of software for identification of logical formats
Criteria for archive formats has been created, a total of 22 points to check in order to estimate formats suitability for long-term digital preservation. The criteria have been ranked after requirements, important and advantage where the condition requirements are a minimum requirement and must be met for a good archive format.
An evaluation of five format registers has been done. The format register that fulfilled the examining points best was PRONOM.
A test of four software identifying files has been carried out. After testing 25 different types of files with shifting results, the best programs turned out to be DROID and JHOVE. DROID achieved the best result with an accuracy rate of 60%. However, none of the programs operates perfectly.
