What are "metadata" and how are they embedded in 3D files?

Metadata in 3D files are descriptive data that provide key information about the 3D model (e.g., creator, dimensions, materials) and are typically embedded during creation or editing using 3D modeling software. They act as "digital labels," enhancing organization and searchability by detailing attributes like file format, creation date, or geometric properties, often stored in standardized data fields within the 3D file’s structure. Common 3D tools (e.g., Blender, Maya) support embedding: users can manually input metadata (e.g., project names, version numbers) or enable automated embedding during export, ensuring completeness for efficient asset management. In short, metadata simplifies 3D asset retrieval, with embedding integrated into modeling or export workflows across software platforms.
