Portable Node-cluster format for mods

[lightonflux]

There are some mods that put clusters of nodes (also called houses) in your map. Insta-build or similar name.

I think it would be useful if minetest had an official format which describes such clusters of node, so people can easily exchange them.

E.g. You build a house over several month and want bring it in a new world. Or you want publish a structure so devs could use it to integrate it in their mods.

You would still need some tools to extract a cluster from a world.
An official format would guarantee that mods could easily exchange such structures.

The current "standard" format for exchanging structures is WorldEdit schematic (.we) files, created with the WorldEdit mod. There's also the new Minetest Schematic format (.mts), but I don't know much about it.

Edit:
P.S: you may want to clarify a bit the title as it's a bit misleading (I thought it was a question about the internal mapblock format on disk or something like that).
