At the very least, we need to start building up a comprehensive list of possible relations.
I'm using standalone notes for entering observations and ideas. I then link to related references. It would be very useful to be able to describe the relationship of each related link to the the note. Currently my main interest is to indicate if a reference supports the observation or idea. The descriptions used need not be anymore verbose than a tag.Does this help?

Your idea is more practical but how difficult is it to implement?
