[Digikam-devel] What do we want to store in the database?

I think Multiple Comments is essential. But also comments need to be
qualified more than just a simple text stream. Gilles mentioned 4
strings to be stored but I'm not sure what they all are. My suggestion
would be:
 * Source
 * Who/Author
 * Language
 * Comment

Here the Source would 99.99% of the time be "Digikam" but hopefully this
interface can be exposed via e.g. Facebook/Flickr via Kipi plugin and
under these circumstances the Source would be set accordingly. Language
I think should be optional seeing as external comments may not have this
information associated with them.

Tags, (as Gilles also pointed out). With the addition of a "region"
attribute (simple rect is probably sufficient here c.f. Facebook -
simplicity wins) as per http://bugs.kde.org/show_bug.cgi?id=146337


And another new one for you:
- key/value pairs

Some form of generic key/value pair storage system for every image,
album and tag. This would be to allow 3rd party plugins via kipi store
important information/configuration paramaters. Actually, possibly more
sensible is a blob of data instread, in which we can store an XML
kconfig dump although this would not allow easy searching... (e.g. it
would be quite useful for a kipi plugin to say "give me all images with
foo = 42".

This needs more discussion but I've often mentioned it in the past so
not a bolt from the blue.
