Hi Anton. Just to point out that this is about adding XMP information to

linux looks like exiv2 will do it.
There's a lot of artificially generated umbrage here.
The UNIX principle of "each thing does one thing and does it well" makes no
sense other than in a UNIX/Linux context because of the interprocess
communication and management tools.
To a UNIX/Linux programmer a program spawning off a child process that does a
specialized task and returns the result to the parent is quite natural because
of the co-processing and 'pipes' nature of the OS and libraries.
And yes this feature is available in the shell.
(See the section on 'Coprocess' in the man page)
And yes you can set it up so both processes stay active and control passes back
and forth.
And yes you can do this with GUI-dom.
The question is not "can you" but "should you".
Elsewhere the developers of DT have written on the evils of modifying the EXIF
information. q.v.
