I’m just wondering if there’s any strategy to link to a post in an instance agnostic kind of way.
Take for example this post which originates in !lemmy@lemmy.ml.
If someone sent me that link but I did not have a lemmy.ml account, then I can read it but not participate.
If I have an account at lemmy.world then it’s not trivial to find that post on that instance. I can’t just edit the url because the post ID is not the same. I’d have to navigate to lemmy.world/c/lemmy@lemmy.ml and find the post from that feed. This might be possible for recent posts but becomes very difficult with any posts even a little stale.
My understanding of “how lemmy works” is very naive, but I assume it’s not possible to generate UUIDs for posts. That being the case you’d need separate lookup servers that maintain lists of urls for posts and can translate between them.
A link like [this](/c/lemmy@lemmy.ml) will work for website users on instances with at least one person subscribed to that community. There is an open issues to generalize this so that clicking the link doesn’t crash Jerboa, and another one to load data from the remote instance instead of just 404ing. I know that’s not amazing news, but this is an open source project under active development.
Posts cannot be universally linked across instances as each instance has a different id, correct. I’m not sure anybody’s thought of a way around that, even before considering dev time. Definitely a longer-term issue to tackle.
