I see.

About EXIF in RIFF i get your point and really like to see it in
gstreamer.

Than other question. For short time there was some sort of call to all
developers to use tracker as backend for management programs like
f-spot, rhythmbox ... i like tis idea. 

But now after i took a look to the source of tracker i see you make own
extractors for tiff, jpg and png. some times you use litexif for this.
What is about RAW image formats? gstreamer is not answer for this.

I think it will be real challenge to maintain it by your self. So it
make me worry that app like Solang will take some years before it will
be useful to manage photos.
