Re: [Gramps-devel] Edit Image Exif Metadata addon

[Rob H. <rob...@gm...>]

Dear John and Nick:

Ok, to be able to separate what we are talking about to make sure that I am
understanding you...

There are eight different object's in the database (Person, Family,  Events,
Places, Source, Repository, Media, and Note),  and the media object within
the database can be edited by the media editor...

Exif metadata can be viewed by MetadataViewer in the MediaView's bottombar,
and it can be viewed/ edited by "Edit Image Exif Metadata" in MediaView's
sidebar...

Tags and Attributes can be edited/ created by Gramps...  "Edit Image Exif
Metadata" can also create/ edit anything that the media editor can by
accessing the DbTxn...

It would be easy to be able to save the media path within the Exif metadata,
but we would need to isolate and find an Exif key that no one uses and save
the file path to it...

Nick Hall, do you know of an Exif tag that could be used for this
purpose...?

Sincerely yours,
Rob G. Healey
