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
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 decrease the density of the tables describing the of the 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:

  1. Description – summary description of the Use Case.
  2. Variables – the main Processes and Items referenced in the Process Actions.
  3. Workflow – expressed by the main elements of Process Actions

MMM-TEC is based on the notions of:

  1. human – operating in the Universe
  2. User – representing a human operating in an M-Instance as a replica of the human or as an autonomous agent.
  3. 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.
