Move one IPTC field content to another IPTC field within XMP files under OS X ?

[Yoms]

Hello,

I have many XMP files generated while traveling with an iPad app.

The content of the IPTC field "<photoshop:Headline>" should actually be in the IPTC field "Sublocation". And the IPTC field "<photoshop:Headline>" should finally be empty.

How can I move the content of this IPTC field to the other, recursively over all XMPs located in several subfolders under Mac OS X ?

Maybe, if I cannot move them straight, it can be done in 2 steps : copy content from one IPTC field to the other, then erase from the origin IPTC field which would be the equivalent of a move command.

Thanks a lot.

Try this:

exiftool "-iptc:sublocation<iptc:headline" -iptc:headline= FILE

where FILE is one or more file and/or directory names.

This will move the Headline tag and delete the original headline.

I tried this :

exiftool "-iptc:sublocation<iptc:headline" -iptc:headline= _GH_0318.xmp

And got this :
Warning: No writable tags set from _GH_0318.xmp
    0 image files updated
    1 image files unchanged

By the way, here is the result of a "more" command on the XMP.

How bad is it ?

**EDIT**


After some researches, I tried this command:
exiftool "-iptc:sublocation<-XMP-photoshop:Headline" -XMP-photoshop:Headline= _GH_0318.

Looking at my XMP, I figured out that the Headline was not the IPTC one, but the XMP Photoshop Headline.

Well, that is the result :
Warning: Tag 'sublocation' does not exist - _GH_0318.xmp
Warning: No writable tags set from _GH_0318.xmp
    1 image files updated

It's true, in the original XMP, there is no IPTC:sublocation field. So, it did not copy anything. But the erase of Photoshop Headline did work.

So I cannot copy it anymore since it's gone. Fortunately I made a test directory with copies.

I assume, I first need to create the IPTC:sublocation field, then make the copy, then clean the headline.

OK.  If you're using XMP files then you're not talking about the old IPTC IIM format (which is what ExifTool refers to as IPTC), but instead the new IPTC4XMPCore (which is XMP format).  IPTC:Sublocation maps into XMP-iptcCore:Location, and IPTC:Headline maps into XMP-photoshop:Headline.  So the command you want is this (note there is no dash after the "<"!  This would have caused problems for you.):

exiftool "-xmp-iptcCore:Location<XMP-photoshop:Headline" -xmp-photoshop:Headline= *.xmp

So you were very close.

ExifTool automatically backs up the originals, so even if you deleted the headline you could always recover it.

I'll try this ! Actually, I was still looking for the right location ! So, in Lightroom 4.4 I imported a RAW file (everything is DNG) then generated the XMP. I wrote "Dude" in the sublocation field within LR4.4 and figured out that it was the iptc4xmp:Location you mentionned. So even closer. At least, I tried to find by myself :-)

BTW, I really find this confusing all this mess between XMP, IPTC and so on...

I try your command and will let you know !

Thanks

[Yoms]

It worked !!! So many thanks for your kind help :-) You've made my day!
