xmp Sidecar files

[kuumaur]

Hi,
thank you very much for your work to this app.
It looks like, that I am not able to use your App correctly.
I have a lot of photos in my Nextcloud.
Most of the jpg/cr2/org files have xmp sidecars, made by Darktable and Xnview.
I thought the metadata app would show me some details out of the xmp sidecar files.
What did I wrong?

Thanks in advance

Versions and Information:
Nextcloud 23.0.0
Metadata 0.15.0
Debian 11 x64
MariaDB
PHP 7.4.25

Thank you for using the app.

At the moment, sidecar files are supported for RAW files only (as per #21).

Would it be possible for you to submit some samples? Would be helpful in development and testing.

Yes, I saw this Issue (#21).
It's for Sony Camera RAW-Files.
I do not want to bother you. I think I am using the App wrong or I have the wrong expectation.
Sure, I can give you some more examples of RAW-Files and .xmp-Files.
I am not sure about if that would add value to my workflow.

I am working with XNView and Darktable.
Both Tools operate with .xmp-Sidecar-Files.
Some attributes are compatible between both tools, most of them are not.
I use XNview MP to upload my photographs from SDcard to my Harddrive. I do a quick review of all the photos incl. rotation etc. and I add a first rating to them.
The Photos are synced to Nextcloud Storage.
What do I want to achieve is, that I want to do the rating from more than from one place.
For example, from a Tablet-Computer or my Phone.
Not sure how to send you the Examples of other RAW-Files, like Canon, Panasonic, Olympus. These files seem to be too big for Github.

PS: If I look further down the road, that would end in a kind of Photo Metadata editor App. I assume that was not your intention.

Examples for Rating:

Rating by standard xmp:

xmp:Rating="2"

Rating by color labels (Darktable):

darktable:colorlabels
rdf:Seq
rdf:li0</rdf:li>
rdf:li1</rdf:li>
rdf:li2</rdf:li>
rdf:li3</rdf:li>
rdf:li4</rdf:li>
</rdf:Seq>
</darktable:colorlabels>

Example .jpg File plus .xmp-Sidecar File
