A while back I was talking about it with friends.
Another question indicates a few meanings of the "meta-" prefix. Considering that "meta" means, in simple words, "about itself" (like how metadata is data about data), what would be the appropriate prefix to mean the opposite relationship?
It seemed to us that "meta" raised a concept to a new level, and we were wondering what prefix would, conversely, lower a concept to another level. Is there another prefix I could use to cancel out the "meta" in "metadata" to get back to "data"?
