That would be fine.

I've just submitted to cvs repo small changes adding support for
multiple IPTC tags. The syntax for above example is:

        $T(IPTC.Keywords) = 'LKAB malmlok tåg transport industri

I've used ' ' as a keywords separator. Is it ok?

Now i do not understand you.

Do you mean to have ' ' around every keyword?

I think i read someware that semicolon is used in
many apps as delimiter between IPTC keywords. I have
also seen IPTC in pictures where all keywords where
written as one semicolon separated value, insted of
multiple values. That would be quite in line with
spreadsheet-apps and plain text databases.

Though the specification on:

"2:25 Keywords
Repeatable, maximum 64 octets, consisting of graphic char-
acters plus spaces."

There does not seem to be specified how to separate
keywords when all of them is presented/viewed in one row,
i guess that is up to the application in question.
So how to deal with files containing more complicated
data like:

 2:025:00 Keywords  Free software
 2:025:01 Keywords  Gnome Commander; GCMD; file management
 2:025:02 Keywords  Piotr Eljasiak; Marcus Bjurman

Anyway, i do not think this is that useful in advrename.
IPTC is a lot more useful for finding, searching and
categorising images. When you have 100 Gb of images,
or even 15 Gb as i have, the problem is not filenames...
And i guess that goes just as well for huge collections
of mp3 or other multimedia where the content is not text
and thus not searchable with ordinary tools.

But now when you got it working in advrename, i guess
you have some sort of foundation to get it working in
the search dialog, and from there one can view/listen,
drag n drop, do filemanagement tasks, and (in future)
pick files to save in a "cart" insted of copying them
to a (for the purpose created) folder. Ohh, does
advrename work on searchresults? I have never tried that
(to late to test now zzzz).

I will test your latest changes tomorrow and get back
about that, plus some other things regarding, programs,
scripts and plugins i have been thinking about.
