Comment on How does lemmy fit into the fediverse?
pyzn@lemmy.world 9 months agoBut arent other services just structured to differently? Like if we have upvotes on lemmy how could they translate to favourites on mastodon.social as a metrik?
One fav=one upvote afaik. I’m not sure how downvotes work.
The biggest difference is if it’s group or individual-oriented. Lemmy does the post to group thing. Friendica’s group function does the group thing. Friendica also does single actor posts, like Mastodon and the micro bloggers. I’m not sure how they’ve solved the lemmy to mastodon thing, but it was initially not federating because Mastodon didn’t support the group function, or lemmy didn’t support the single actor posts - either or.
Lemmy downvotes are ignored by Mastodon and Kbin.
I don't really know the details of how they would translate from app to app, but I do know that ActivityPub is specifically designed to allow all of its apps to pull the same information. If an app utilizes ActivityPub, it inherently has the capability of displaying all of its components.

It all uses the ActivityPub protocol, so interoperability depends on what end points are used. In this case, favorites on Mastodon and upvotes on Lemmy use the same one as far as I understand it, so they are compatible. If you see a post from a Mastodon user on Lemmy and upvote it, it should translate to a favorite on their end.
