glTF and collada have "extras" for unstructured metadata. glTF now also has
structured metadata:

https://www.khronos.org/blog/pervasive-asset-metadata-in-3dcommerce

based on the XMP standard.

https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_xmp_json_ld

has the details.

To avoid further confusion, let me emphasize this is completely unrelated
to library node functionality.

Hope this helps, Andreas
