[Shotwell] Problem and question importing from f-spot

[shuihuzhuan at free.fr]

Hi,

I have a weird problem importing my database from f-spot and I don't know how to workaround this.

Few months ago, I changed a lot of tags in my f-spot database (deleted some, renamed others, changed tags on a lot of photographs). But although f-spot had already written tags in those photo files in the past (with an older version of f-spot), for a lot of files it didn't succeeded and so wrote an XMP sidecar file instead (with an error message). More than 7000 files are concerned (the whole database is more than 15000 files).

So I have a lot of files with wrong tags in the EXIF/IPTC or whatelse fields (in the sense that they have previous tags), and the right tags are in an XMP sidecar (and in f-spot database).

When I try to import the database from f-spot, the tags and the hierarchy is imported from f-spot, but shotwell (0.11.2) also seems to read the tags in the files and I get a mess with right and wrong tags in shotwell tag's hierarchy.

For completly deleted or renamed tags, they are added at the root in shotwell's tags hierarchy, so it's not too hard to find and delete them in shotwell again.
But for tags only removed on some files and still used for others, I'm not sure how they are handled by shotwell :
1. if they are not recognised as already in shotwell's tags hierarchy, I will find them at the root and I can clean the photo's tags => Ok
2. if they are recognised as already in shotwell's tags hierarchy and added to that tag, I won't see them at the root and couldn't clean the photo's tags => NOk

>From what I've already read in the mailing list, I think shotwell handles imported tags from files like option 1 (at least for 0.11.2), but I'm not sure. Could you tell me if I'm right?

Thank you for your help

PS : I can't do a lot of testings because shotwell systematically crashes during f-spot import (though it worked fine with version 0.10), but that's another problem...
