PieFed v1.4 will have Stack Overflow-like functionality: the person who posted a question will be able to choose which of the replies are the answer, by clicking the green tick icon in the bottom left. Chosen answer(s) then have a highlight and a green tick at the top of them.

This is off by default - communities have a checkbox on them that needs to be toggled to turn it on. So only some communities will have it.

To Lemmy instances, these questions and answers will look just like normal posts and comments, without the highlight and tick. So people using Lemmy will be able to contribute.

Designating which comment is an answer involves federating a new Activity:

         "id": "https://piefed.social/activities/answer/hgb4iO4b8UAFRTn", 
         "type": "ChooseAnswer",  
         "actor": "https://piefed.socialz/u/rimu", 
         "object": "https://piefed.ngrok.app/comment/224",  
         "@context": ["https://www.w3.org/ns/activitystreams", "https://w3id.org/security/v1"],  
         "audience": "https://crust.piefed.social/c/linux_questions",  
         "to": ["https://www.w3.org/ns/activitystreams#Public"],  
         "cc": ["https://crust.piefed.social/c/linux_questions"]  
}

        I’d like to see the answer property on the thread containing the ID of the marked answer. Any chance that this would be possible?

          Ideologically, you’re right.

          But since announcing that feature I also started, finished & announced another major one and am now eying up the next one.

          Onwards!

            There’s also the issue that the comment could be on a service that doesn’t support this (which is all of them bar Piefed), so this won’t be set. At least if this was on the post, it’s within your remit and can therefore control for it.
