MWG-Extensions of MWG regions - some info

[herb]

Hello Phil,

it is wonderful, that Exiftool is back and that everything is ok with you.

Now to MWG-extensions struct: On your internet site is stated: "no tags known"

I found an image with such tags on digiKam forum.
The image was posted because of problems that digiKam has with this image made with an Apple Iphone 6.
I exported all XMP-tags into a sidecar xmp- file, which I attached to this post.

This is only an info about MWG-extensions.

Best regards

I believe the reason it says "no tags known" is because the extension can contain almost any XMP tag.  From the docs
   This structure may contain any top-level XMP tags, but none have been pre-defined in ExifTool

So it's not that the tags aren't known, it's that there are so many options that it would be a considerable effort to add with very little usefulness.

Exactly.
