1    Introduction

A standard that only specifies Functionalities may create a significant burden to implementations serving very different needs because the technologies supporting some Functionalities may be costly but seldom used. Profiles defines groups of Functionalities that serve specific application areas while providing a level of Interoperability.

In the following Functional Profile is shortened to Profile.

Table 15 lists the currently identified Actions, Items and Data Types supported by a Profile. Cells with text in italic indicate a classification of Items, Action, and Data Types.

2       Profile structure

The current features MPAI Metaverse Model – Architecture Profiles are:

  1. Identified Profiles are Baseline, Management, Finance, and High.
  2. The High Profile includes the Management Profile that includes the Baseline and Finance Profiles.
  3. The Profile structure includes hierarchical Profiles and one independent Profile.
  4. The Baseline, Management, and High Profiles have Levels, currently identified as: Audio only, Audio-Visual, and Audio-Visual-Haptic. The Finance Profile does not have Levels.

This is depicted in Figure 3. The next Sections provide additional details.

Figure 3 – The currently identified Functional Profiles

Each Profile allocates the supported Actions, Items, and Data Types. While the identified four Profiles serve well the needs conveyed by the identified Functionalities, the consideration of more Functionalities in the future may lead to an increased number of Profiles and potentially Levels.

3       Baseline Profile

The Baseline Profile enables a human equipped with a Device supporting the Baseline Profile to allow their Users to perform the functions of Table 16. Currently, this Profile has the following Levels: Audio only; Audio-Visual; and Audio-Visual-Haptic.

Table 16 – Functions, Actions, and Items of the Baseline Profile

Functions Action Items

Identify Item Identify Item, Identifier
Author Entity Author Item

Place an Entity at MLoc, with perception MM-Embed Entity, MLoc
Stop perception of Scene MM-Disable Entity, MLoc
Make available an Object to a User MM-Send Entity
Render at ULoc an Entity at MLoc MU-Render Entity, MLoc, ULoc
Make scene at ULoc available to a Device UM-Capture ULoc
Make Data of a Device available to a Process UM-Send Device, Process
Transfer Data between Processes MM-Send Message

Place Entity @ MLoc UM-Render Entity, MLoc, ULoc
Send an Entity at an MLoc to a Device MM-Send Entity, Device, MLoc
Place, Animate, and Render Model at MLoc Track Model, Stream
Store Item MU-Send Item

Roughly speaking, this Profile supports applications in a basic form for e.g., lecture, meeting, hang-out.

Table 17 lists the Actions, Entities, and Data Types of the Baseline Functionality Profile.

4       Finance Profile

The Finance Profile enables a human equipped with a Device supporting the Baseline Profile to allow their Users to perform the functions of Table 18. The Finance Profile enables a User to Post Assets and make Transactions. As depicted in Figure 4, this Profile is independent of the Basic Profile. The Financial Profile shares some technologies with the Baseline Profile, but the Finance Profile introduces technologies and does not support other Basic Profile technologies. Currently, this Profile does not have Levels.

Functions Action Items

5       Management Profile

The Management Profile enables a controlled ecosystem by supporting all Actions, Items, and Data Types of the Baseline and the Finance Profiles in addition to some others of its own. It enables a human equipped with a Device supporting the Management Profile to allow their Users to perform the functions of Table 20. As depicted in Figure 4 the Management Profile is a superset of the Baseline and Finance Profiles. Currently, this Profile has the following Levels: Audio; Audio-Visual; and Audio-Visual-Haptic.

Functions Action Items
