Metadata
Custom data and tags
Metadata attaches custom key/value data to nodes, meshes, or the asset (e.g., author, version, semantic tags).
How it works
- Stored as extensions, user properties, or dictionaries depending on format.
- Values may be strings, numbers, bools, arrays; schemas improve consistency.
Use cases
- Asset tracking, LOD tags, pipeline state (e.g., export flags)
- Search/filter in asset libraries
- Provenance and copyright metadata
Interoperability notes
- Unknown keys may be dropped; prefer standardized extensions where possible.
- Document namespaces to avoid collisions across tools.
