XMP-pur:Permissions

[TomaszZogala]

hello,

I'm a fairly new ExifTool user, but I'm becoming a big enthusiast. I would like to ask about a proper way of setting xmp:pur-permissions. I would like to achieve an effect like the example on the https://www.w3.org/submissions/prism/#_Toc46323689 but I believe I failed.

trying to find an answer I tried commands like:
exiftool -addtagsfromfile @ "-XMP-pur:permissions={distributionChannel=print, code=C1}" "-XMP-pur:permissions={distributionChannel=web, code=C2}" image.jpg
or
exiftool -XMP-pur:permissions=[{pur=[{distributionChannel=web,code=c2}]},{pur=[{distributionChannel=print,code=c1}]}] image.jpg

so I would like to ask how can I do it properly?

There may be some confusion between XML and XMP.  I think your reference is for XML.  ExifTool defines XMP-pur:Permissions as a Bag of simple strings, but it is a structure in your XML example.  Do you have an example file with XMP containing this information?

Might the data they want to write be qualifiers?

See pur:expirationDate with date and qualifier

Ah yes.  That could be it.  Darned qualifiers.  I have to figure out how to handle them.
