MPAI Metaverse Model – Technologies (MMM‑TEC) – A Framework for Interoperable Metaverse Ecosystems

What MMM‑TEC Enables

The MPAI Metaverse Model – Technologies (MMM-TEC ) standard defines a technological framework that enables humans, represented by software entities called Users, to interact seamlessly between physical and virtual worlds.

With MMM‑TEC, a human operating in a virtual world can:

  • perceive and interact with the physical world (“the Universe”)
  • create and use digital representations of objects (called Items)
  • perform actions within a virtual world
  • trigger actions in the physical world based on virtual conditions and
  • interact across multiple virtual worlds.

 Core Concept: The M‑Instance

At the centre of MMM‑TEC is the Metaverse Instance (M‑Instance), a virtual environment where uniquely identified software entities interact by performing actions on uniquely identified digital objects:

Processes – software entities performing actions – Users are a type of Process representing humans.

Items – digital representations of things (physical or abstract).

H‑Users are operated directly by a human and A‑Users operate with some level of autonomy.

How These Interactions Work

Processes in an M‑Instance interact through Actions, which are structured expressions describing what is to be done and on what. A Process may also request another Process to perform an Action on its behalf by issuing a Process Action (PA). This is done when the Process lacks the required capability, when it does not hold the necessary rights, or when rules prevent it from acting directly.

Rights, Rules, and Trust

MMM‑TEC regulates behaviour with Rights – what a specific Process may, may not, or must do – and Rules – what a class of Processes may, may not, or must do on classes of Items and Processes.

Before Processes interact, trust must be established. This is handled using the MPAI Process Instance Trust Framework standard. Once trust is in place, Processes can exchange data securely, metadata can be attached to indicate usage permissions, and interactions can be executed safely and in compliance with Rules.

 From Interaction to Economy

MMM‑TEC supports the creation of virtual economies through a variety of Items, such as Assets representing capabilities, provenance, and value; Service Pricing Models describing which services are available and how they are charged; and Licences expressing rights and conditions for use.

Interoperability between metaverses

A key capability of MMM‑TEC is interoperability between different M-Instances. This is enabled by the Resolve Process Action, which allows a Process in one M‑Instance to establish a session with Processes in other M‑Instances.

 A Rich and Extensible Model

MMM‑TEC currently defines around 100 types of Items, covering a wide range of use cases. Some Items are strictly defined, while others are described using Qualifiers, allowing flexibility. For example, a machine learning Item can specify model type, format, regulatory status, validity and certification, or a media Item can specify the format.

 Status and Implementations

MMM‑TEC is currently at Version 2.2. Reference software exists for Version 2.0. New implementations are under development using Unity-based environments and Open Simulation. Metaverses built on different platforms will be able to interoperate seamlessly within the MMM‑TEC framework.

Looking Ahead

An important MMM‑TEC complement will be provided by ongoing work on the A‑User Architecture, which defines the internals of autonomous agents in an M-Instance.

Key Takeaway

MMM‑TEC provides the foundation for interoperable, trustworthy, and economically enabled metaverse environments allowing users to move from isolated virtual spaces to a connected and actionable metaverse ecosystem.
