I think I’m missing something here. Has anything changed in the form of the table in your example here compared with your original email? It looks the same to me (I had assume the use of a colon prefix in the first three columns was an indication that those fields were storing IRIs). I still think all the issues I raised apply, and would appreciate your thoughts on them.

Thanks,
