(Informative)
1 Introduction
This Informative Chapter verifies that MMM-TEC supports s a variety of M-Instance context Use Cases.
The following conventions are used throughout:
| Acronym | Meaning | Acronym | Meaning | Acronym | Meaning |
| MLoc | M-Location | MTransaction | Model Transaction | MData | Model Data |
| SA | Spatial Attitude | MRights | Model Rights | ULoc | U-Location |
The following Service abbreviations are used to increase the readability of the tables describing Use Case workflows:
| Service Name | Acronym | Service Name | Acronym | Service Name | Acronym | Service Name | Acronym |
| Author | AUSrvc | Identify | IDSrvc | Land | LDSrvc | Resolve | RESrvc |
| Communicate | COSrvc | Interpret | ITSrvc | Presence | PRSrvc | Rights | RTSrvc |
| Execute | EXSrvc | Locate | LCSrvc | Register | RGSrvc | Transact | TRSrvc |
All Use Cases include the following:
- Description – summary description of the Use Case.
- Variables – the main Processes and Items referenced in the Process Actions.
- Workflow – expressed by the main elements of Process Actions
MMM-TEC is based on the notions of:
- human – operating in the Universe
- User – representing a human operating in an M-Instance as a replica of the human or as an autonomous agent.
- Persona – an avatar animated by a User.
To make use case descriptions less congested, the same name may be used to indicate a human, a User, or a Persona. The context will clearly identify to which of the three entities the name refers to in a specific context.
2 Friends meet in the metaverse
2.1 Description
Human1 registers with an M-Instance. Friend1 (User of Human1) acquires a land parcel and a room,
tracks its Persona at a reference location (MVS), moves to the parcel, places the room, and enters it.
Friend1 invites Friend2. Friend2 accepts the invitation, receives access rights, and moves to the room.
After some time, Friend2 leaves and Friend1 revokes the granted rights.

11 Co-design across metaverses
11.1 Description
Two Designers operate in different M-Instances and collaborate on the design of a shared object.
Each Designer registers with their respective M-Instance and creates or accesses a design workspace.
A design object is created in one M-Instance and made available to the other through resolution mechanisms.
The Designers exchange updates and modifications, ensuring that both representations remain consistent.
Design changes are transmitted across M-Instances, possibly requiring format or capability conversion.
The Designers collaborate in real time by modifying the shared object.
After completing the co-design session, updates are consolidated and access rights may be revised.

12 Selling assets on a Marketplace
12.1 Description
A Seller registers with an M-Instance and owns a digital Asset.
The Seller requests a Marketplace Service to post the Asset by submitting a Service Pricing Model and granting posting rights.
The Marketplace lists the Asset and allows Buyers to discover and request purchase.
A Buyer may select the Asset and perform a transaction through the Marketplace.
The Marketplace coordinates payment transfer and Rights assignment: the Buyer receives usage rights, the Seller receives payment, and the Marketplace receives service fees.
After the posting period expires, the Marketplace stops listing the Asset and the Seller may regain full control of its Rights.

13 Emergency in Industrial Metaverse
13.1 Description
A Worker operates in an industrial environment connected to an M-Instance.
Sensors continuously capture operational data from machinery and transmit it to the metaverse.
An anomaly is detected by analyzing the captured data. An Emergency Service interprets the condition as a potential fault and triggers an alert.
A Supervisor is notified and accesses the virtual representation of the industrial system.
Corrective actions may be executed remotely or locally through actuators.
After the emergency is handled, the system returns to normal operation and relevant rights and states may be updated.
