MPAI, the international, unaffiliated, and not-for-profit organisation developing standard for AI-based data coding [1] established in 2020, has developed a range of Technical Specifications and Technical Reports [2] – 18 and 2, respectively – covering a variety of application domains that can benefit from the use of Artificial Intelligence (AI).

Two standards relevant to this document are

  1. Technical Specification: AI Framework (MPAI-AIF) [11] specifying initialisation, dynamic configuration, and control of AI applications implemented as AI Workflows (AIW) composed of AI Modules (AIM). An overview and the full text of the standard are available.
  2. Technical Specification: MPAI Metaverse Model (MPAI-MMM) – Technologies (MMM-TEC) [12]. An overview and the full text of the standard are available.

MMM-TEC assumes that

  1. M-Instances are metaverse instances implemented in conformity with MMM-TEC.
  2. An M-Instance is populated with Processes acting on Items representing “things” in the M-Instance.
  3. User is a Process operating under the responsibility of a human, either
    1. Directly – Human User (H-User), or
    2. Without direct control – Autonomous User (A-User).

MPAI believes that

  1. A-Users able to interact with Users – both A- and H-Users – are attractive components for M-Instances.
  2. A component-based A-User standard can accelerate the development and deployment at scale of A-Users.
  3. MPAI has the necessary capabilities and technologies to start a new activity called Pursuing Goals in metaverse (MPAI-PGM).

The MPAI-PGM standard project called Autonomous User Architecture (PGM-AUA) is planned to include a series of standards. The first of them is Use Cases and Functional Requirements: Pursuing Goals in metaverse (MPAI-PGM) – Autonomous User Architecture (PGM-AUA) targeting implementable architectures for A-Users. As these require a large set of technologies that can be made available by AI Modules integrated in an AI Workflow operating in the Standard AI Framework, PGM-AUA re-uses its considerable set of technologies developed in the contexts of its standards – most of them based on AI-Framework – when relevant to PGM-AUA. Other technologies have been used or developed for PGM-AUA.

In all Chapters and Sections, Terms beginning with a capital letter are defined in Table 1. All MPAI-defined Terms are accessible online. All Chapters are Normative unless they are labelled as Informative.
