I'd use a mixture of those: captions/comments to describe the picture, and
use tags for persons, locations, type of events and such (things that can be
captured accurately in 1-2 words).
As you are going to do it with other people giving you the information,
putting the information in the correct field on the spot might be difficult.
You might want to record (audio) what the others are telling you about a photo
for later reference, and clean up notes and tags in a second pass.

For formats like PJG, PNG, TIFF, Digikam can write tags, captions,
comments etc. to the file as metadata. In that case the data will stay
associated with the image. (and, back up the images before adding the
tags/comments, just in case)

Tools like exiftool or exiv2 can extract metadata (Exif, ITCP, XMP, ...)
in a readable format. After that, there's a lot of possibilities to use those
data (scripting...). A lot will depend on the number of images you're dealing
with, but from your signature, I guess you know how to do that part...
Good luck,
Remco
