Born Digital Still Images Similar lifecycle to digitized. MD not always stored. Primarily use NISO MIX format (includes EXIF, GPS). Images are numerical representations - different image formats compress differently - some need special MD. NISO MIX contains many fields that are seemingly unimportant but may be valuable as evidence. NISO MIX also includes many fields completely unintelligible to the layman, referenced or not. The previous two factors can spell trouble if the preservationist is not an expert! EXIF would help, but there is not a 1:1 ratio of information. Metadata is meant to help understand transformation, not to “step backwards” to recreate images although this is possible with sufficient detail. Addison 4 DEC 06
