Model Extensions (MEX)
The AUTOSAR model can be extended via Model Extensions (MEX) to support
the type-safe editing of predefined AdminData.
AdminData is a core feature in AUTOSAR to add arbitrary content to a
model. It consists of cascaded Sdg elements, which then hold the
content or references to other model elements, for example in Sd or
SdxARRef elements.
To be able to extend certain defined elements, they need to be declared
beforehand via SdgDefs in their SdgClasses.
In the DaVinci Developer Adaptive those previously mentioned definitions and elements are used to extend certain predefined elements in model (MEX), which are relevant, but not limited, to MICROSAR Adaptive.

The following chapters provide an overview of what AdminData with
their Sdg, Sd and SdxARRef elements are, how SdgDefs and
SdgClasses are used to define the according extensions of elements in
the model, as well as detailed explanation on the MEX concept in the
tool.
