Hi Stefan,

after taking a closer look at class.tx_dam_indexrulebase.php again, I 
have to revoke my previous comment.

If you overwrite $meta['fields']['category'] in the function 
proccessMeta, it will be overwritten again at some later point. Changing 
  the title field in processMeta for example works perfect. As I don't 
have much time to finish the project I'm currently working on, I'm 
unable to research the problem more precisely.

Maybe the following (very dirty but extremly useful) testing-code helps 
you a little bit:

function postProcessMeta($meta, $abs) {
	exec('echo "'.print_r($meta, true).'" >> /home/thorsten/exiftest3.txt');
	exec('echo "'.print_r($abs, true).'" >> /home/thorsten/exiftest3.txt');
	}

At the point where the function is called the datasets corresponding to 
the indexed files are allready inserted into the database and you can 
read their uids from $meta['fields']['uid']. This makes it very easy to 
execute an updatequery. The variable abs contains the full path to the 
indexed file. The function gets called for every single file.

Of course this additional query will cost you script-runtime and thereby 
it isn't a beautiful solution - but I think it will be my way to do it 
because of the lack of time.
