[Digikam-users] Re: Digikam not writing metadata (caption/tag/rating)

[Gilles Caulier]

Yes, i know the problem. We have already an entry in bugzilla about.

The goal is to cache metadata writing until user ask to push it to
image. It's easy to do as all metadata are already recorded to
database.

I see Aperture and Lightroom working like this on my macbook. When
application is shutdown a dialog appears to ask if metadat must be
sync with DB. If yes, process can take a while until application
shutdown really. It's acceptable.
