exempi — command line tool to manipulate XMP metadata


exempi { -h | [ -R ] [ -x ] [ { -w | -o <file> } ] [ { -g <prop_name> | -s <prop_name> -v <value> } ] } <files>


-h: show this help

-R: don't reconcile

-x: dump XML

-X: file(s) is XMP

-w: write in place. Only for -s. Not compatible with -o.

-o <file>: file to write the output to.

-n <ns> <prefix>: set the prefix for a namespace.

-g <prop_name>: retrieve the value with prop_name.

-s <prop_name> -v <value>: retrieve or get the value.
<files> the files to read from.


The source code hasn't been audited for security. The command line tool doesn't have a strong input sanity checking easier.

Be careful not to run the tool as super-user. Be careful if you decide to use it in an online (web) application.

Patches and suggestions welcome.
