Hi Nathan,
I had put that discussion to the side, to avoid really filling up peoples'  mailboxes!
But welcome, I do care about the issue.

Sounds good.
But does not really address the problem.
Where do you put the seeAlso?
In the same Graph/store, with the same provenance/licence?
The particular predicate is not the issue - it is how you communicate the provenance/licence etc. of the knowledge, and if it gets the same provenance/licence as the data it is about through being put in the same place.
