Hey!
This is a BBEdit-question, but I first need to give a little background
to it. :-)
As all photographers here already know, the metadata to the photos lives
in a suplimentary XMP-file.
Here is a sample of a XMP-file for one of my photos, where I filled in
the so called *IPTC-keywords* in Photo Mechanic:

The individual data is the creation-date:

photoshop:DateCreated="2018-05-10T13:35:00.03"
xmp:CreateDate="2018-05-10T13:35:00.03"

and the IPTC-keywords:

<rdf:li>Ben</rdf:li>
<rdf:li>Mina</rdf:li>
<rdf:li>Tom</rdf:li>
<rdf:li>Vlad</rdf:li>

Another background-information that probably all of you know: there is
no relation between the IPTC / XMP - keywords and the Finder / macOS -
tags.
And this exactly is my problem.
I need to input somehow / somewhere the metadata to my photos, but I
don't want to make this twice in order to have this information present
in the IPTC-keywords AND in the Finder-tags as well.
This is not new at all: Google-ing about "*copy IPTC-keywords into
Finder-tags*" or viceversa I've found a lot but all of it involved in
one step or another the EXIFtool, a command line utility that reads and
writes photo-metadata… and this doesn't scale very well (I have A LOT
of photos: about 220,000 pics that are more than 2 TB big!) and it is
slow, because the EXIFtool have to read the metadata from the photo.
So my idea is to take care or the IPTC-keywords in Photo Mechanic (this
would create a XMP-file as the one above for every photo I have) and
then - and here comes BBEdit! :-) - *somehow* transfer the data from the
XMP-file (that is in the end only a text-file!) to the Finder-tags.
Now finally to my question (sorry for the length!): How could I
- take each IPTC-keyword (delimited by the tag < rdf:li >, see above)
and
- write this IPTC-keyword into a Finder-tag
for every photo in a folder?
Ideally I'd have a script, point it to a folder full of photos and
BOOM!, after this every photo would have the same Finder-tags as the
IPTC-keywords!
Could you please help me with this?
Thanks in advance!
Regards,
Vlad
