The current MARTE specification contains 11 composite aggregation Stereotype properties typed by a Stereotype. This is not allowed by UML (Clause 12.3.3.4) : "The type of a composite aggregation Stereotype Property cannot be a Stereotype (since Stereotypes are owned by their
Extensions) or a metaclass (since instances of metaclasses are owned by other instances of metaclasses);".

The type of aggregation shall be changed to "reference". There are 11 changes to be done in HRM subprofile and one in Time subprofile.

Remove composite aggregations types for Stereoypes properties

Change the aggregation types from composite to reference for Stereotypes properties. These changes should be done on figures: 9.29, 9.30, 11.4, 11.5, 14.65, 14.66, 14.67, 14.68, 14.69, 14.72 and 14.73.
These changes have impact on the XMI file.

The Carbon footprint is an interesting property for Hardware resources as well as Software ones. In fact, nowadays it is important to evaluate the CO2 footprint of a system (a laptop, a data center…).
This criteria is depending on the usage of the resources (mainly for the software resources).
We suggest adding a new property « co2Footprint » either in the “ResourceUsage” Stereotype” or in the Resource Stereotype for more general cases.

The unit that measures the carbon Footprint is Kg of carbon dioxide equivalent (KgCO2e) per Year. This implies the addition of a new dimension in the Marte::MeasurementUnits «CarbonUnitKind» with new unit « kgCO2e » as well as a new NFP_Co2footprint that inherits from NFP_Real with unit = kgCO2e.

The value of the CO2Footprint can be proportional to the origin of the energy used to produce the device in kWh eqC02. The proportional factor is country dependent https://app.electricitymaps.com/map

Include a CarbonFootprint property

Include a CarbonFootprint property to ResourceUsage.
