Minor request
I had to do a dive into the XMP-xmpDM Dynamic Media tags (https://exiftool.org/TagNames/XMP.html#xmpDM) to try and figure out what they were used for. It seems that they are used with Adobe Experience Manager (https://experienceleague.adobe.com/en/docs/experience-manager-65). I think that link should be added to the XMP-xmpDM to make it easier to find the source of these tags.
I think these tags may be in wider use than just by Adobe Experience Manager. But I should add a link to the specification (https://developer.adobe.com/xmp/docs/XMPNamespaces/xmpDM/). Would that help?

I'll dig a bit deeper then, but all I could find at the moment was the Experience Manager.
Results so far
Searching Google, Bing, and Yandex on adobe dynamic media "XMP-xmpDM" to specifically target the XMP-xmpDM name gives me these results
Google only gives about 3 pages total, Bing gives more, but devolves into randomness after the 3rd/4th page. The same with Yandex. Removing "XMP-xmpDM" shows nothing but Adobe links and also becomes random after the 3rd/4th page.
Most of the pages are either the Adobe pages about Dynamic Media or copies (so many copies) of the exiftool XMP page or exiftool code.
There is an Exiv2 page on the tags
The IPTC Video Metadata Hub page (https://www.iptc.org/std/videometadatahub/recommendation/previous-versions/IPTC-VideoMetadataHub-mapping-Rec_1.2.html) has references, but no programs. There are similar references on the W3 Ontology for Media Resource page (https://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/WD/Ontology10.php#d0e9670), but again, no programs.
There is the Elodie management program (https://github.com/jmathai/elodie), but that originally used its own XMP-elodie tag until you suggested here (https://exiftool.org/forum/index.php?msg=37074) to use the XMP-xmpDM:Album tag.
There's a Go package the implements XMP data, but it looks like it more or less implements most of the tags from the XMP tags page.
According to this post (https://exiftool.org/forum/index.php?msg=89715), it appears that Lightroom might read XMP-xmpDM data, but not allow editing. A quick test with Adobe Bridge shows it displays this video data.
So I can't really find another major program other than Adobe ones that use these tags. The link to the specification is probably the best bet and this post will probably end up in any searches on the subject.
Thanks. Will do.
