How to refer to posts in an "instance-agnostic" manner? (self.main)

4 comments fedilink hide all child comments

If I want to link to a community X on a Lemmy instance Y.zzz, I know I should use the link /c/[email protected], which will redirect to the copy of the instance on the server where the user has the account.

What is the analogous way to link to a post? For example this post has address lemmy.ca/post/1866360 but what link should I give to users on another instance, so that they can see the post in their instance?

As far as I know there's no current way to do that. When two instances federate with each other, the posts and comments, etc, get replicated on each instance. One consequence of this is that the same post ends up with different ids. I'm sure a solution could be developed, as the instances must keep a cross reference so they can match comments coming from different instances to the correct post. But as far as I know, there's no UI way to link in an instance agnostic way.

Thank you! Good to know it's not possible at the moment anyway :)

Hopefully we'll see Lemmy improve on that front.

Use the post checksum as key info and refer to it at each site by a lookup.

Sadly that means some coding AND database mods.
