When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific metadata (e.g. geo-tag or creator) is not currently possible. For AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any metadata fields unless the user selects ALL of the checkboxes in the export module’s preference options.
– darktable release notes
You are not selecting all of the checkboxes.
It looks like it may have been part of private tags, synonyms, or hierarchical tags.
The rest I had selected.
Thanks for the feedback.
Test it and let us know that it works for you.
I don’t understand why .xcf is being referred to as if it were an image like TIFF, etc.
According to Harvey’s ExifGUI none of the .xcf files created by the GIMP 2.10.34 on my computer has any EXIF data, only some meta-data.
It’s simples, really.
I export my image to GIMP, then export it to Flickr. I want GPS data.
Does that make sense?
Did it work?
It certainly did. Thanks.
It was one of three selections that I mentioned. I may work backwards to see if I can isolate which one exactly.
Don’t bother. The instructions are clear: ALL of them need to be checked for these image formats for any metadata to be exported.
You may find that exporting metadata fails again as soon as you uncheck any one of them.
I’m not sure the presence of metadata in itself is important, the routine that writes the metadata may just skip when one of the boxes is not ticked
