1. What is not working as documented?

If I understood https://github.com/photoprism/photoprism/issues/747 correctly, Photoprism should already be able to import faces from xmp sidecar files generated by digikam.

2. How can we reproduce it?

Steps to reproduce the behavior:

Tag people on Digikam
Export metadata to sidecar files
Import into Photoprism
Faces not found. Not all face tags are found either.

My library has pictures in all kinds of formats.

Here's an example of a sidecar file whose face is not indexed:

3. What behavior do you expect?

I would expect all faces in the "people" tab with their names and/or at least the names to be searchable.

No face is in people and many are not in tags (this might be related to digikam's hierarchical tags though).

4. What could be the cause of your problem?

Photoprism might be expecting a slightly different format to be parsed.

5. Can you provide us with example files for testing, error logs, or screenshots?

Included in section 2.

6. Which software versions do you use?

(a) PhotoPrism Architecture & Build Number: x64 - 230309-e58fee0fb

(b) Database Type & Version: SQLite

(d) Browser Types & Versions: Brave

(e) Ad Blockers, Browser Plugins, and/or Firewall Software? No

7. On what kind of device is PhotoPrism installed?

Not a performance issue

8. Do you use a Reverse Proxy, Firewall, VPN, or CDN?
