Technical Specification: MPAI Metaverse Model (MPAI-MMM) – Technologies (MMM-TEC) V2.1 – in this and other MPAI documents also called MMM-TEC V2.1 or MMM-TEC:

  1. Specifies the technologies enabling an M-Instance to interoperate with clients and M-Instances independently designed and implemented in conformity with MMM-TEC, namely:
    1. The Processes operating in an M-Instance that capture Data from the Universe and actuate Items in the Universe as R-Items.
    2. The Items, i.e., the Data Types with their Qualifiers recognised in an M-Instance.
    3. The Actions and Process Actions that a Process performs on Items. and Processes
    4. The Protocols enabling a Process to communicate with other Processes.
    5. The MPAI Metaverse Model Profiles.
    6. The MPAI-MMM API.
  2. Makes available the MMM-TEC Reference Software demonstrating the operation of an M-Instance in one of the twelve Validation Use Cases included in MMM-TEC.

Note: MMM‑TEC defines the roles, semantics, and architecture where tamper‑evidence is REQUIRED or RELEVANT, but it does not dictate which cryptographic or storage technology must be used to achieve it. It does this because the standard must:

  • Remain technology‑neutral.
  • Support diverse implementations (centralised, decentralised, hybrid).
  • Avoid premature choices that would expire quickly.
  • Permit government‑controlled, enterprise‑controlled, or open‑metaverse deployments.
  • Allow innovation in trust and audit mechanisms.

All MPAI Qualifiers are specified in Technical Specification: Data Types, Formats, and Attributes (MPAI-TFA) V1.4 for consistent use across all MPAI Technical Specifications.

MMM-TEC has been developed by the MMM Group of the Requirements Standing Committee. MPAI may develop MMM-TEC extensions or new Technical Specifications in the MPAI Metaverse Model work area.
