The MPAI-MMM Scripting Language – MMM-Script in the following – serves the double purpose of providing:

  1. A handy tool to describe the Actions performed by Processes in an M-Instance.
  2. A compact form that a Process can use to request another Process to perform Actions.

1       MMM-Script for Action Description

The performance of any Action in an M-Instance can be expressed as:

Process ActsOn Item | DataMdata | Media

At Service | User | MLoc | ULoc Where Item ends up being located with SA
By Service Used to perform Action
From Address | ULoc Address, ULoc where the source is located
Into Item Action leads to
Of User Item refers to
To Address | Device | Process | User Item/Process where Items ends up being placed
With DataMdata | Stream Additional Item required to perform Action

Note: SA is used as a compact form for Spatial Attitude.

Table 5 lists the possible combinations of Actions. Composite Actions are divided into elementary Actions.
