This is the public page of the MPAI Metaverse Model (MPAI-MMM) standard providing technical information.  Also see the MPAI-MMM homepage.

Technical Specification: MPAI Metaverse Model (MPAI-MMM) – Architecture V1 is the first metaverse specification, published on 2023/09/29. Rather than specifying technologies that are often immature and evolving, MPAI-MMM – Architecture specifies the Terms, the Operation Model, and the Architecture composed of Processes performing Action on Items. It also specifies Functional Profiles.

Processes are: App, Device, Service, User.

Actions are:

  1. General Actions: Register, Change, Hide, Authenticate, Identify, Modify, Validate, Execute.
  2. Call a Service: Author, Discover, Inform, Interpret, Post, Transact, Convert, Resolve
  3. Manage Entities:
    1. Universe to Metaverse: UM-Animate, UM-Capture, UM-Render, UM-Send
    2. Metaverse to Metaverse: MM-Add, MM-Animate, MM-Disable, MM-Embed, MM-Enable, MM-Send
    3. Metaverse to Universe: MU-Actuate, MU-Render, MU-Send, Track

Items are:

  1. General: M-Instance, M-Capabilities, M-Environment, Identifier, Rules, Rights, Program, Contract
  2. Human and User: Account, Activity Data, Personal Profile, Social Graph, User Data
  3. Process Interaction: Message, P-Capabilities, Request-Action, Response-Action
  4. Service access: AuthenticateIn, AuthenticateOut, DiscoverIn, DiscoverOut, InformIn, InformOut, InterpretIn, InterpretOut
  5. Finance: Asset, Ledger, Provenance, Transaction, Value, Wallet
  6. Perception: Event, Experience, Interaction, Map, Model, Object, Scene, Stream, Summary
  7. Space: M-Location, U-Location

Ten Use Cases have been studied and successfully applied to verify the practical applicability of MPAI-MMM – Architecture standard:

  1. Virtual Lecture
  2. Virtual Meeting
  3. Hybrid working
  4. eSports Tournament
  5. Virtual performance
  6. AR Tourist Guide
  7. Virtual Dance
  8. Description
  9. Virtual Car Showroom
  10. Drive a Connected Autonomous Vehicle.

Four Profiles have been identified: Basic, Finance, Management, and High.
