@trwnh And I always thought that this is some of the LD patterns that easily make sense: to globally identify each term used in your data by an IRI *and* to use the same IRI as a link to the term's documentation. Apparently, I was wrong.
OTOH, I get it when people don't think they need (to understand) JSON-LD but I also think it is not too much to ask to follow community patterns by slapping a context link into your JSON.
