Title: Recognizing a Species of XMP
Post by: blue-j on April 18, 2022, 07:15:41 PM
PLUS' Universal Picture Licenses are .xmp files.  Is it possible for ExifTool to recognize them, like with a custom config?  They do always only contain PLUS fields, in RDF.  See attached for simple examples.

I didn't check all the tags in those file, but it looks like they are all supported.  See the PLUS tags page (https://exiftool.org/TagNames/PLUS.html#XMP).

Indeed.   What I mean is how to recognize it from other XMP documents.  - J

Ah, gotcha.

Raw XMP isn't my strong suit, but I don't think there's anything that exiftool can directly read to identify it as  different. If you copy all the tags from one of your files into a new xmp file, the data is pretty much the same, just formatted differently.

The only thing I can think of would be a user defined tag that check to see if all the PLUS tags were in the file.  Basically a giant IF that checks for the existence of the 81(?) tags.  But even then, you can't check to make sure there are no other XMP tags.

Phil will have to weigh in on what might be possible.

I don't think that this is something that ExifTool should do.  As far as I can see, this is an XMP file.
