Metaverse Metadata Directory
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.
The MVMD Approach
MVMD establishes formal integration pathways between established metadata standards through a structured architecture.
- 1
Metaverse Asset Standards
Leveraging established standards like glTF, USD, VRM, and C2PA which provide specialized capabilities for different aspects of metaverse assets.
- 2
Schema.org & JSON-LD
Using Schema.org vocabulary with JSON-LD to create a standardized metadata foundation.
- 3
MVMD Integration Profiles
Specific profiles that define precise integration patterns for various metaverse use cases.
- 4
Digital Assets Implementation
Enabling NFTs, digital assets, and data with consistent metadata handling.
- 5
Interoperable Ecosystem
Creating a seamless experience across metaverse platforms, digital asset stores, and Web3 explorers.
