Thank you for the fixes. I think the markup is aligned enough (mostly from the author information) that we can do deduplication on our side now using some combination of author and timestamp. To let you know what I plan, I’m going to essentially merge the extra Question type into the DiscussionForumPosting and the Answer type into the Comment on our side.
It would be advisable to eventually figure out a way to do this on your side. Either integrate it directly into Discourse for native typing in the markup to pick between DFP or Question OR use node ids to append the extra type on the markup generated by the core forum platform (so that the OP will be co-typed Question +DiscussionForumPosting). It’s probably eventually going to be disallowed or at least marked invalid in reporting by our systems, but I understand some practical reasons why this is necessary currently as we’re figuring this space out.
