It is not dogmatically following any patterns, but looking at some modding tools of Bethesda games is interesting for how game data as entities or forms in this case is structured. Battle tested model for extendibility and you already have real game data to get examples. Don't know how close these patterns would fit Unity, but I would suspect a large overlap.
