just giving my point of view on this matter. I think modifying picture metadata is a tricky topic, and one has to decide what geekie will be: - a picture viewer - a picture editor ? - a picture metadata editor ? (eg: fix the date in the picture exif) - a picture collection manager (with sorting/classification capabilities...) in the first case, all operation should be read only (or explicitly warn the user). The second and the third are not that different : I would tend to consider a change of the exif date or orientation as a modification of the picture. At last, I would expect the following features from a picture manager,(with decreasing priority): - let people organize their files as they want - a clear policy regarding picture modification, such as: " we never modify a picture without asking", "we never modify a picture at all" or "we never modify without creating a new revision" - real picture versioning (based on rcs, svn or so) - multiple version picture handling: RAW+JPEG and duplicate detection (one could keep a checksum of all the revisions in order to find duplicates against old revisions too) - picture classification (user tags + timeline) - offline support (keep a local low resolution version ?) Regarding the user-defined metadata such as tags and comments, my (current) point of view is that tags should not go in the picture. They are mainly meant to organize a picture collection as a whole. Moreover, some picture formats cannot hold them. They should be stored externally in text files/XMP sidecar or in a database. We can also hope that the folks from freedesktop/Xesam/tracker will eventually provide a desktop-wide solution to this problem.Regarding the comments, I have no idea yet... Well, what do you think of keeping pictures in a svn repository ? regards ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geeqie-devel mailing list Geeqie-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geeqie-devel
