Adam,
Would it be possible to just pick one of the two conventions for local
images, and then possibly reverse the convention on the exported photo
depending on the target of the export?

Luc,
thanks for the patch. We've spent a fair amount of time at Yorba thinking
about which metadata fields to write titles to. Unfortunately different
programs use these fields in different ways. See the tables at
http://redmine.yorba.org/projects/shotwell/wiki/PhotoTags
If we don't write to Iptc.Application2.Caption, then some programs (most
notably Picasa) will not be able to read titles exported from Shotwell. On the
other hand, some Apple programs (iPhoto and Picasa) use
Iptc.Application2.Caption to store descriptions, so as you pointed out we could
clobber those when writing. I don't see any ideal solution here at the moment.
We generated the tables on the wiki page above by testing various programs a
couple of years ago. It would be interesting to refresh those tables to see if
programs' behavior has changed. I really hope that different programs can
converge on a single metadata tag for storing captions and another for
descriptions. Xmp.dc.title and Xmp.dc.description would be good candidates for
this.

Hi Adam,
The new build worked fine, thanks for the quick reaction.
Then I patched the following because I would like shotwell to leave the Caption
tag alone when setting the Picure Title (I use Caption with other programs for
a long description on some photos). Eventually I'd like shotwell to handle
both fields but that would be a much heavier change. Initial testing shows
that it works well in my workflow (e.g. Flickr Uploader can set both fields on
my uploads -- not if I use shotwell's plugin though).
Thanks for this new shotwell. With this patch I'll be able to test much more
extensively by using shotwell as my main photo management application, now that
I'm confident it won't overwrite this Caption field.
So far I've only done limited testing but had no problems.

Luc,
The build was broken - sorry about that. I've just committed a fix, so you
might want to try again.
