And of course let’s not forget [glTF](https://www.khronos.org/gltf/), which [is already being integrated with Slicer](https://discourse.slicer.org/t/transferring-models-using-gltf-2-0/7064). It’s more graphics-oriented than medical, but the features and community support, not to mention compactness and extensibility are impressive. No reason we couldn’t propose an extension to embed some things like coordinate system reference (probably LPS by default) and other useful things like anatomy codes.
