I’m trying to figure out how to get the comments of a post given a link to it using ActivityPub.
Based on reading the ActivityPub spec, I thought comments were federated via the replies key of the ActivityPub Object.
This works for Mastodon posts, but not for Lemmy (nor Pleroma). As an example
curl -H "Accept: application/activity+json" https://lemmy.my.id/post/79514 | jq
doesn’t contain a replies key. Yet the comments are federated to Mastodon somehow.
What is going on? How can I get the comment?
I understand exactly what you’re saying; you can get the parents but not the replies in that situation.
I’m just saying that in your situation (e.g. someone I follow on Mastodon likes a Lemmy post) it would be convenient for me as a user to be able to view the replies to that Lemmy post, but I cannot necessarily do that because Lemmy does not include
replies.I expect it does, from the lemmy API. But from the ActivityPub api, it doesn’t make sense to.
