The reason is that our Lr import code is less than stellar. It reimplements some code we already have elsewhere without actually supporting all the things it copies. So most of the metadata that we normally read from XMP files is ignored. If anyone wants to fix that: use the stuff from exif.cc in lightroom.c.

If you don't need the Lightroom processing being imported just rename your XMP files to have the file extension in its name, for example: IMG_0001.CR2 + IMG_0001.XMP -> IMG_0001.CR2.XMP Then the metadata, like title, gets read, but the Lightroom settings aren't. If you need both then you could try the following (make backups of the XMP files first): Copy the Lightroom XMP files to the dartable place, so you have two XMP files per image, one with the image file's extension in the filename, one without. Both files have the same content. Then import the images. On import the file in the darktable location will be read and the metadata applied. Then when you open the image for the first time the Lightroom XMP will be read and the settings will be imported. Then you can delete the Lightroom XMP for that image. The downside is that you have to open every image in darkroom to have its settings being applied. Or alternatively, export all images once. 10x10 pixels size is enough, with high quality export disabled in preferences. That should also makes darktable read the Lightroom XMP files. Thumbnails need to be regenerated but that's probably possible some way, too. Caveat: I only tried that in a limited test right now, I can't promise that it works reliably. So better check some random samples before deleting the Lightroom XMPs. > Cheers > Ralf Tobias
