 This repository holds reference implementations for [Usd](https://openusd.org/release/index.html) [asset resolvers](https://openusd.org/release/glossary.html#usdglossary-assetresolution). The resolvers are compatible with the AR 2.0 standard proposed in the [Asset Resolver 2.0 Specification](https://openusd.org/release/wp_ar2.html). As the Usd documentation offers quite a good overview over the overall asset resolution system, we will not be covering it in this repository's documentation.
