Single Image Validator

This validator checks whether a single TIFF or JPEG2000 image meets HathiTrust specifications.

It will also report whether any missing metadata or incorrect technical characteristics may be remediable, or whether the image must be rescanned or regenerated from a master image. Many issues can be automatically remediated on ingest to HathiTrust for packages created in the "Cloud Validator" submission format. Other issues may require manual remediation before submission.

We recommend ExifTool by Phil Harvey for changing metadata in images, ImageMagick for repairing TIFF images, and Kakadu (commercial software; demo for noncommercial purposes available) for generating JPEG2000 images.
