MDDE Taxonomy

The MDDE taxonomy provides a structured classification system describing how MDDEs are instantiated, transformed, and governed across systems.

Core MDDE

• Identity Layer
• State Layer
• Modification Governance
• Audit & Provenance

Derivative MDDE

• Content-derived entities
• Context-bound entities
• Transformation-generated entities

Operational MDDE

• Renderable entities
• Executable entities
• Policy-restricted entities

This taxonomy reflects real-world MDDE deployments in dynamic content pipelines and secure device-bound systems.
