Has anyone wrote a script that writes any info to sidecar?

[Andrey Goreev]

Hello,

Thank you all for your earlier responses.

Here is how I transfer xyz(c) coordinates writen into video files to
digiKam database so far:
https://youtu.be/QpBJaSIPMCk

The "Copy GPS to clipboard script" reads the coordinates using mediainfo
and converts them from something like this:
©xyz                                     : +50.9003-114.0125/
to something like this:
geo:50.900300000,-114.012500000
Then I select the video in digikam, press Ctrl + Shift + G (for some reason
you can only see "G" on the video) and paste the coordinates.
Works as a charm but it is not automated.

Next step would to automate this process which means the scipt would read
the xyz(c) tag using mediainfo and write it to the sidecarfile.

Sidecar looks like this:

<?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?>
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="XMP Core 4.4.0-Exiv2">
 <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
  <rdf:Description rdf:about=""
    xmlns:xmp="http://ns.adobe.com/xap/1.0/"
    xmlns:exif="http://ns.adobe.com/exif/1.0/"
    xmlns:tiff="http://ns.adobe.com/tiff/1.0/"
   xmp:CreatorTool="digiKam-5.6.0"
   exif:GPSLatitudeRef="N"
   exif:GPSLongitudeRef="W"
   exif:GPSVersionID="2.0.0.0"
   exif:GPSLatitude="50,54.0180000N"
   exif:GPSLongitude="114,0.7500000W"
   exif:GPSMapDatum="WGS-84"
   tiff:Software="digiKam-5.6.0"/>
 </rdf:RDF>
</x:xmpmeta>
<?xpacket end="w"?>

As you see, the coordinates will need to be converted again.

Actually exiftool is able to see more GPS tags written to file and they
look more similar to what digiKam is expecting to see in XMP:
...
[QuickTime]     GPSCoordinates                  : 50 deg 54' 1.08" N, 114
deg 0' 45.00" W
...
[Composite]     GPSLatitude                     : 50 deg 54' 1.08" N
[Composite]     GPSLongitude                    : 114 deg 0' 45.00" W
...
[Composite]     GPSPosition                     : 50 deg 54' 1.08" N, 114
deg 0' 45.00" W
...

Do you think that will be easy to accomplish?

So far  tried inserting:
   exif:GPSLatitudeRef="N"
   exif:GPSLongitudeRef="W"
   exif:GPSVersionID="2.0.0.0"
   exif:GPSLatitude="50,54.0180000N"
   exif:GPSLongitude="114,0.7500000W"
   exif:GPSMapDatum="WGS-84"
to an XMP file but digiKam did not recognize it.
