The differences between a given region of the world at a given time and the same region some time later.
> Schematic origin
The origin of the schematic itself. This is always (0, 0, 0). Any schematic generated from the main Minetest world MUST be translated such that the negative X, Y, and Z corner of the defined region to be converted to a schematic is (0, 0, 0) in the generated schematic file.
> Offset
An offset, expressed as a `Vector3`, that MUST be applied to a schematic upon loading it back into the world, though implementers MAY offer an option to disable this (but applying the offset MUST be enabled by default).
> BNF
[Backus-Naur form](https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_form). Used to formally describe the file format.
