#17 Wrong use of "subject" EXIF tag

[Ulf Rompe]

We seem to have interpreted the definition of the EXIF tag called "subject" wrongly. We thought it was meant as an abstract like the subject field in RFC822, while other people tend to use it to store keywords.
We should do the same to be able to interact with F-Spot for example.

"When in rome, behave like the romans."

So we will possibly implement a gate between the "keywords" and the "subject" tag. Gating information from "subject" to "keywords" has the benefit that Gallery2 is then able to make use of F-Spot tags.
