Re: [Shotwell] Repairing the event field in the database

[Alan Pater <alan pater gmail com>]

XMP sidecar files are the standard way of storing image metadata
outside of the image files themselves. Shotwell does not currently
have the option, but there is a open feature request:
https://bugzilla.gnome.org/show_bug.cgi?id=716228

Shotwell uses the exiv2 libary to manage metadata. You can access that
programmatically to create XMP sidecar files. Or send in a patch for
Shotwell to do that :-)

exiv2 itself will have greatly enhanced json support, starting with
version 0.25, which we hope to get out the door soon.

There is also exiftool:

That is an excellent article on managing photo metadata in general,
whatever tool you use.

You might also be interested in what the Metadata Working Group has to
say about mapping data between the various historical standards:
