With respect to IPTC and EXIF data, the question isn't so much about whether
to replicate it or not as it is about whether you want to permit searches to
be based on such data. If the data is available only buried within the
image, you do _not_ want to expose that field within search queries;
conversely, if you want to be able to search on it, you need to expose it
within the repo.
