What happens to world capability data when the player enters another dimension? 1.16.5

[Turtledove]

Say I have some data that I serialize/deserialize in the Overworld using world capabilities' NBT. When the player then enters the Nether, does that data get saved to NBT when the Nether loads its own world instance, and able to reload when the player exits the Nether, or does it just get destroyed?

Each world has its own data and as such, serializes and deserializes their data separately. Anything saved to one world is for that world and anything saved to a different world is for that other world.

I know that, but you're saying that when we switch between dimensions A->B, the data in dimension A is saved, and reloads normally when we return to A from B?

Yes

Ok that's good to hear
