Universal Scene Description is a framework for interchange of 3D computer graphics data, see wikipedia article.
This use defined file formats like: .usd, .usda, .usdc, .usdz.
NVIDIA team use this definition particularly for Universal Scene Description: Universal Scene Description describes geometries, materials, physics, and behavior representations of 3D worlds and is the best open and extensible standard ....
The platform for connecting and developing OpenUSD applications is NVIDIA Omniverse.
NVIDIA Omniverse™ foundation apps are best-practice implementations of native Universal Scene Description (OpenUSD) apps for 3D data aggregation and large-scale world simulation. Users can easily extend and customize the apps with custom-built extensions, or use them out-of-the-box.
What is 3D data aggregation:
A process in which data is searched, gathered, and presented in a summarized, report-based form, data aggregation helps organizations to achieve specific business objectives or conduct process/human analysis at almost any scale.
Let's a simple and good example by sending data from one external program like Mineways to export physically based materials and use them interactively at high quality in the free Omniverse Create program:
