Tagging images (Exif/iptc)?

I want to write a simple tool to tag my images. I was looking at the pyexiv2 library, which is built on top of the exiv2 lib.
However, I do not know which metadata key to use to store tags. I tried these:
1. Exif.Photo.UserComment
2. Iptc.Application2.Keywords
3. getComment() - which is some comment that is neither exif nor iptc. Not sure where this comes from.

However, when I open the image in question with gqview, I see nothing in the exif information. Also, I added a comment with gqview, and I can't see it using pyexiv2.

tl;dr - which exif/iptc key is for adding tags/keywords to an image?

EDIT: I looked at the tag list and both options 1 and 2 are for storing user tags. However this question remains - which one gives more compatibility with image viewers and more unversal?

P.S.: Feel free to move to general programming if needed.
