jaotteluna

Jaotteluna is a fictional concept used in speculative fiction and collaborative world-building to describe a systematic approach to organizing information about the Moon within a narrative or role-playing setting. The term combines Finnish jaottelu, meaning "partition" or "classification," with luna, the Latin word for "moon." It is not a term used in professional astronomy or planetary science.

The concept originated in online writing and conlang communities in the early 2010s as a flexible naming device for a modular data framework. Writers and game designers adopt jaotteluna to ensure internal consistency when detailing lunar features, histories, and their societal implications. It is typically applied as a mnemonic schema rather than a formal standard.

A typical jaotteluna framework divides lunar information into domains such as geology and terrain, orbital context and illumination, surface processes, resource potential, and cultural or narrative significances. Practitioners use the categories to generate scenes, track development over time, and align world-building elements across plots or campaigns. While widely used in fan-made settings, jaotteluna has no official endorsement beyond its communities and serves primarily as a creative tool.
