Fiction:Draconid Imperium/Planetary Classification

With over ten million inhabited systems under its control and a further several million used as remote or automated research, material extraction or interstellar survey, the Draconid Imperium utilises a comprehensive planetary classification system to take into account a wide variety of factors.

With the importance of industry being a cornerstone element of the Imperial fabric, planets are classified using a three-point code that explains the scale of settlement, a planet's primary economic output and the scale of local industry. For example a planet with a large population of two billion that specialises in manufacutring will be a Class IV-MG-C while a small frontier that acts as the breadbasket for a larger region using robotic farm-hands would be registered as a Class II-AG-D.

As well as worlds the Imperium has colonised or annexed, the system is also used to classify various pre-contact planetary societies under the Imperium's purview and even foreign planets.

Composition
A fourth (typically not used in economic records) is a rating of the planet's physical composition. Unlike the other ratings, the composition rating is sued to define a planet's physical composition.
