//! # Resource management utilities
//!
//! The semantics, materials and textures are commonly referred to as *resources*.
//! The resources are mapped to geometry boundaries with [`mapping::SemanticMap`], [`mapping::MaterialMap`] and [`mapping::TextureMap`].
//! These maps are version agnostic, while the Semantic, Material, and Texture definitions are versioned.
//! The resources are managed by resource pools that are stored in the `CityModel`.
