That's a harder proposition than you might think. On the one hand, UUIDs are mathematically guaranteed to be universally unique, which is great. On the other hand, there has to be some way to go from a UUID to a particular post, which suggests a lookup table, but the federated nature of Lemmy basically makes that impossible, since there's no assurance that any instance is aware of any other instance.
No, it only suggests an additional field in the
PosttableIt already works like that, but slightly worse because post IDs aren't the same across instances. If you search a newly-created community from another instance here, you just won't find it until it's synced, despite its URI being unique.
Thinking about it, it would be possible to have an URI for posts like
post:${id}@instance.com, similar to how user URIs and community URIs are made. This way, you could open/post/1772651on lemmy.world orpost:1772651@lemmy.worldon, idk, lemmy.blahaj.zone or something.
