repeats the filename multiple times.  You only need to provide the file name once.  Also, you try to set XMP-cc:License to multiple values.  Only the last assignment works, as it overrides previous assignments.  See Note #1 under the -TAG[+-^]=[VALUE] option.

repeats the filename multiple times.[/tt] option[/url].

yes, intentionally. i dont want to create ambiguity by stating different licenses on both copyright and xmp.

i think its better to drop updating xmp. or is any other tool to update multiple xmp tags.

To clarify, my point is that all of this

is the same as just this.

Only the last assignment is used.  License 1-3 will not appear in the file.  You are only stating one license with that command.

The XMP-cc:License, by default, can only hold 1 URI.  Exiftool will write multiple if you assign them all at once, but will give a warning
