Google's Picasa stores user-added metadata (keywords, tags, ratings, whatever) in the IPTC 'field' of JPEG files (equivalent to MP3 ID3 space). --> see
Picasa - Wikipedia, the free encyclopedia
I think this is a good idea, as it doesn't tie you down to any one program -- if you want to use another program in the future to manage your photos, you can just switch to it and, since IPTC is a standard, the new program will recognize all your previously-inputted metadata and can run with it.
iPhoto is great in most respects as far as I can see, but crucially it stores all metadata in its own proprietary, centralized database, meaning that you're tied to iPhoto pretty much forever if you annotate an appreciable number of photos (also, a central database store is vulnerable to corruption).
So does anyone know of a iPhoto-equivalent program that manages its metadata Picasa-style?
At the moment I'm considering running Picasa under Windows on an intel mac, but I'm hoping there's some Mac OS X native app out there that might be suitable.
thanks for any tips,
