But Known didn't handle it because the microformats boiled down to a p-in-reply-to with a bunch of objects inside it. It's worth going back and making sure we support the full set of expected indieweb variables.

Thanks Ben. Tagging @Phyks too; he was helping me test this issue earlier.

yep, same thing here. While trying to debug it yesterday, I found some unassigned PHP variables, #699. After the fix for issue #699, I got an email notification when firing the webmention, but nothing shows in Known (no comment). Did not have time yesteday to debug it further, but you seem to have clues :)

The notification should be triggered at the point at which it's saved, so this suggests a template issue. I'm checking it out.

Mentions should now correctly display as of the latest commit (although new mentions will display a little better).

[benwerd]

I should clarify that this doesn't yet address properly determining mention type when the contents of the reply URL class is a complex structure.

@benwerd I updated to the latest commit. Same thing, notification triggered but nothing displayed in the template: https://known.phyks.me/2015/publishing-through-the-known-api.
