Overview This is a memo on how to add Normalization rules in Archivematica’s Preservation planning. Background When ingesting images with the .jpg extension into Archivematica, there were cases where tif files were not created for preservation, despite having a rule to create tif files for items with Format of JPEG as shown below. I checked the task details from the history screen shown below. The results were as follows. ...
Overview I investigated cases where ImageMagick does not work properly when creating pyramidal TIFFs for IIIF image delivery.

Overview In the following article, I explained how to build an IIIF Image Server using an AWS serverless application. This time, I register a relatively large image and verify whether tile image delivery is possible. Target This time, the target is “Mining Claim Maps” (held by the University of Tokyo Komaba Library). https://iiif.dl.itc.u-tokyo.ac.jp/repo/s/ichiko/document/4120a330-2f1c-4e2c-5d48-21aed4d42704 The original image is a TIF file of nearly 300 MB. Creating Pyramidal Tiled TIFF Referencing the following site, I tried both VIPS and ImageMagick. ...
