All I have just published initial set of updates to the Extension Registry page on the wiki - https://cwiki.apache.org/confluence/display/NIFI/Extension+Registry The initial work was started by Bryan Bende a while back and I hope I’ve managed to incorporate all of his points where relevant. Still work in progress but worth putting it out there to collect initial input. It is indirectly related to the component documentation improvements page https://cwiki.apache.org/confluence/display/NIFI/Component+documentation+improvements so reading through both would help.
Cheers Oleg
