The task is to come up with a pattern for each entity in the model. For example, a village has a commons, a place for shops and services, a transit stop, a pre-school, polling place, etc, all in some relation to each other. Each level will have connections to adjacent levels.
See my page on Christopher Alexander, and his Notes on the Synthesis of Form, and A Pattern Language.
