I really like flickr, but it has the flaw of being a paid service.
Can’t fault them for it, but when it comes to long-term archival of photos, obviously Flickr is not a viable solution.
Pre-Flickr they were usually referred to as “keywords”.
PhotoSuite had them, and they were a really nice feature.
However, in that app and others (e.g. iPhoto), the feature is locked up by a propreitary means of storing the tags. Thus my quest — to find an open way to save tags.
Some sort of XML schema would be an obvious method.
Of course, this need only be used for import/export/archival.
But that’s what I’m all about here: archival. An app would likely keep this data ina a database for quick access and search.
When you archive the photos to cassette/floppy/Magtape/CD/DVD/BD/HD-DVD/whatever, the tags would be saved with them.
Otherwise, tags are a waste of previous time and energy. So, if you know of a standard, open means by which tags can be saved/restored, please let me know!
My Googling revealed nothing.
