metta data with java
Alternatively and much more easily, you can use a library like Apache Commons Imaging or Metadata-Extractor, or run a shell command to read it.

this concerns linux users with gimp
A change causing a crash has been identified in this version, depending on how applications using exiv2 pass data to it: https://github.com/Exiv2/exiv2/issues/2649.

Exiv2 updated with substantial jpegxl metadata feature fixes and additions (finally 🎉)
Complete release notes
-
a good day for jxl (libjxl v0.8.0, and exiv2 v0.27.6)
In addition, this commit isn't available in 0.27.6 yet, so newer JXLs which use Brotli to compress metadata (e.g. files encoded with libjxl 0.7.0) will also show no metadata unless you build exiv2 from the main branch with BMFF (and rebuild dependents of exiv2).

Exif data from image file
Thanks for the reply. I went a little bit deeper to get more out of images metadata using Exiv2/exiv2. It's getting everything from "exif" to "xmp" tags. And it's fairly maintained ! Only drawback, it's not written in GO. So I'm gonna call it using the cmdline ^^.

Up for Grabs
some of these appear to not actually have curated tasks. it lists exiv2 for example which links to an issues tag on github, but it's empty https://github.com/Exiv2/exiv2/issues?q=label%3A%22good+firs...

Issue link to DigiKam support for JPEG XL
"WebP has been supported since 2016. You're right. I should add JXL. We only need to add a few lines of code to support JXL/bmff. JXL/codestream is still being negotiated by the standards committee and will add ICC support. Exiv2 doesn't provide ICC support for every image format." https://github.com/Exiv2/exiv2/issues/1466

How do you install exiftools via command line?
exiv2 is a similar, but different program than exiftool.

Conditionally Batch Edit EXIF Header
Does jhead, exiftool, exiv2, etc., allow me to use a command or a series of commands to accomplish this goal?

Exiv2 now supports JXL/bmff
Great! Reading through issue 1503 though, this support is for EXIF and XMP data in the "container" version of the format. Support for an ICC profile in the "codestream" format (both bare files and inside a container format file) is in issue 1506 and left for future work. So the support is not complete, but a good step forward for the format.
