1        Introduction

This Informative Chapter collects M-Instance Use Cases in different contexts with the goal to verify that MMM-TEC V2.0 supports a range of representative Use Cases thus confirming validity of the Technical Specification.

Note that, unless disclaimed otherwise, a sentence like “A student attends a lecture held by a teacher in a classroom created by a school manager” s to be read as “A User representing a student attends a virtual lecture in a virtual classroom Authored by a User representing a school manager and MM-Embedded at an M-Location”.

2        Use Case Description Language

Metaverse Use Cases involve a plurality of Processes – Users, Devices, Services, Apps – requesting other Processes to perform Process Actions involving a variety of Items and Processes. In a Use Case:

1. Processes (e.g., Users) are sequentially identified by one subscript.
2. Items Acted on by a Process are identified by the subscript of the Process performing the Action followed by a sequential number of the Item.
3. Objects, Scenes, Events, and Personae may be prefixed by S, A, V, AV, or AVH to indicate their Speech, Audio, Visual, Audio-Visual, or Audio-Visual-Haptic nature, respectively.
4. The Location Item where the Actions take place are similarly identified by the subscript of the Process performing an Action at the Location followed by a sequential number.
5. If the Actions are performed at different M-Instances, all Processes, Items, and Locations have a sequential capital letter as first suffix.

For instance:

1. User_i MM-Embeds Persona_j at M-Location_k.
2. User_i MU-Embeds Item_j at U-Location_k.
3. User_A,i MM-Sends Message_j to User_B.k.

All Use Cases assume that Actions are performed in an M-Instance. Action specified in the Universe are specifically noted.

The following conventions are used throughout:

MLoc	M-Location
MData	Model Data
MRights	Model Rights
MTransaction	Model Transaction
SA	Spatial Attitude
ULoc	U-Location

For graphical convenience, the following Service abbreviations are used:

Activity	ACSrvc
Author	AUSrvc
Communication	COSrvc
Execution	EXSrvc
Identification	IDSrvc
Interoretation	ITSrvc
Location	LOSrvc
Parcel	PASrvc
Registration	RGSrvc
Resolution	RESrvc
Rights	RISrvc
Transact	TRSrvc

Use Cases include the following:

1. Description of Use Case
2. Workflow in two parts:
   1. Declarations of all Processes and Items involved
      Note that Model Items are not declared as Items are declared.
   2. Operation of Use Case using the Inter-Process Protocol
3. Elementary Messages used by the Use Case.

The Operation of a Use Case is described by a table whose columns have headers corresponding to the elements of a Process Action. Each Process Action is split in two lines, the first describing the Source sending the message and the second describing the destination sending a response back to the Source.
