Your central hub for discovering and implementing metadata standards for metaverse assets

The Metaverse Standards Challenge

Today's metaverse ecosystem relies on numerous excellent standards working in different domains:

  • glTF handles 3D model representation
  • USD enables complex scene composition
  • VRM specializes in humanoid avatars
  • FBX supports animation and rigging
  • COLLADA facilitates asset exchange
  • X3D enables web-based 3D graphics
  • OpenXR standardizes VR/AR experiences
  • CityJSON provides urban environment modeling
  • 3D Tiles manages large-scale geospatial data
  • C2PA handles content authentication

These standards excel in their domains but achieving interoperability between them requires additional integration work.
