Tags from Capture One are not separated

[nicokaiser]

The bug

Capture One seems to export keywords as HierarchicalSubject in a way different than what Lightroom does:

 <rdf:Description rdf:about=''
  xmlns:lr='http://ns.adobe.com/lightroom/1.0/'>
  <lr:hierarchicalSubject>
   <rdf:Bag>
    <rdf:li>Conference</rdf:li>
    <rdf:li>International conference</rdf:li>
    <rdf:li>JS Kongress 2017</rdf:li>
    <rdf:li>JSK17</rdf:li>
    <rdf:li>München</rdf:li>
    <rdf:li>Munich</rdf:li>
   </rdf:Bag>
  </lr:hierarchicalSubject>
 </rdf:Description>

Immich seems to interpret this as one tag: Conference,International conference,JS Kongress 2017,JSK17,München,Munich
I don't know if this should be saved differently by Capture One, but this behaviour leads to many very long Immich tags for every combination of exported keywords...

5. The Photos has only one tag which contains all of the keywords at once

Additional information

I can provide a full JPEG file and/or XMP if necessary

The same happened to my 70000 photos. I ran metadata update to all and now the tags are not separated any more. What is strange that these tags are originally set by Lightroom. The result is that tags are not usable any more.

Sorry about that. This should be fixed with #12509.

[smoltron]

While it may be fixed, my database stays corrupted. How can we clean the faulty tags and recreate them again? Exctract metadata/All did not delete the faulty tags.

A nice "Delete all empty tags" some place would possibly be nice for the future.

Yeah, we can definitely add something like this.

Yeah, we can definitely add something like this.

So this would be a new feature request, like "auto cleanup tags with no images"? Or can this be done in a trivial DB query?

Already implemented in #12654
