Is there a way to transfer grouped images from one machine to another without transferring the database?

The only way I know is to store the groups in tags and later regroup images. While I was able to write a lua-script tagging the groups automatically I ran into problems, because the amount of tags my (super inefficient) script produced froze darktable when I wanted to filter by tags. I could reduce the tags my script produces without problems, but I wanted to know whether there are any tools that can create this mapping automatically and maybe without the creation of tags.

The main reasons for transferring groups is, because I will shoot some photos away from home and want to tag/group them on my laptop and move the images to my computer when I return home.**When at home a can use the groups to easily recognize images that need to be passed to hugin together.


Thanks

Hi Holger,

I guess this is not possible since grouping is not a property of a single image but a group of images and thus saved in the database. Since I use grouping for different purposes I created a set of hierarchical tags like this:
Image|Series|Panorama
Image|Series|Aperture
Image|series|chronological
Image|Series|Focus
Image|Series|HDR
and the resulting reimported is tagged by
Image|derived|Panorama
Image|derived|Aperture
Image|derived|chronological
Image|derived|Focus
Image|derived|HDR
which of course is a workaround but also gives you some more flexibility and granularity in the overall workflow.

regards
Bernhard
