It's written in N3 for two reasons: 1) it is a syntax that mere mortals can (mostly) manage 2) it
dramatically cuts down on the amount of text (like the number of characters) needed to describe your meta-data.
The example above is probably butting right up against the limit of data you can shove into an Exif
Comment field but it is deliberately verbose and you can win a little extra space by doing
things like removing new lines. If your description is very long you could even stick it in a separate file
and point to it as a external resource. I don't really like those kinds of solutions but atleast a reference to
the data is embedded in the image itself which is a good deal better than having to remember [insert clever
secondary file for image meta-data scheme here]. see also : /usr/local/bin/jhead -ce
