digikam is writing private data as meta-data into the image. Private data is e.g the image history (pathnames, resolution, etc.) I did not find any way to stop digikam from doing this or make digikam to remove this data. I'm using digikam version 3.1.0 Reproducible: Always Steps to Reproduce: 1. Load some image 2. Use workflow feature to a) remove all metadata, b) add some meta-data from a template 3. Same the image 4a. Look at die metadata sidebar: digikam schema contains history. 4b. Verify with independent tool
Remove all metadata will do the stuff, but add template will restore versioning info from XMP digiKam namespace... A wrap around can be to remove XMP only. Template will be also applied to IPTC, with some limitations of course. Else, remove metadata tool must be improved to be able to drop some specific namespace or tags, but it's a complex project...
