The current version of the metadata tool allows users to apply arbitrary sets of actions (eg, a new ID, a comment, plus any annotations or OF values, among other things) to a full page of observations at a time. If you change the per page limit to the max, that’s 200 and you could do 1000 observations in 5 easy actions (although it takes a while for them to actually go through). It is not difficult to install or set up IMO.
I asked Tony directly to tell me whether this was a violation of the machine-generated content policy as I’ve implemented it, and I never heard back.
I am not aware of a way to set “agree” or “disagree” for contradicting higher level IDs through the API but I will look into it and see if I can make it happen; that’s definitely something I’d like to support.
ETA: I figured out how to add the Disable parameter–thanks for prompting me to look into that!
