The massBreakeDown is subdivided in designMasses , fuel , payload and mOME (operating empty mass).

designMass

The design mass is a description from TLARs and can be understand as design criteria.

fuel and payload

The fuel and payload mass are the maximum masses which can be achieved. Full fuel tanks, all passengers on board and full cargo holding.

mOEM

The operation empty mass structure is based on the Airbus Mass Standard brake down [AIRBUS MASS STANDARD 2008]. The operator’s mass empty (OME) is defined by the sum of the following component masses:

• operator’s items
• manufacturer’s mass empty (MME)

Each sub component has the following massDescription which include a:

• Name
• Description
• parentUID
• Mass value
• Mass location
• Mass orientation
• Mass Inertia.

That massdescription can be found at the designMasses direct under each item. At the fuel , payload and mOME under massDescription in each item and sub item.
