    "\n",
    "This Jupyter Notebook is an exploration of SysML v2 from the user perspective. It shows some SysML v2 basics, but mainly focuses on the special features compared to SysML v1 and how they can be used. For a detailed introduction to the textual syntax of SysML v2, I recommend the following PDF: [Introduction to the SysML v2 Language Textual Notation](https://github.com/Systems-Modeling/SysML-v2-Release/blob/master/doc/Intro%20to%20the%20SysML%20v2%20Language.pdf).\n",

    "SysML v1 is primarily known for its diagrams. Although they are only the visualization of the model information and the real treasure of a real SysML model is the model data behind the diagrams.\n",
    "\n",
    "SysML v2 also provides graphical visualizations and additionally a textual notation. Both are equivalent notations and tools can provide editors for both.\n",
    "\n",
    "The SysML v2 pilot implementation has so far only a textual editor and generates the graphical notation. Therefore, some have been under the impression that SysML v2 is primarily textual. This is not the case. Those who wish can use SysML v2 as they would SysML v1 and edit the model using graphical editors only."

Above in the output of the %show command you can see \"[Subsetting (implicit)] PartUsage subparts\". \"subparts\" is a special part from the SysML v2 library. This implicit connection is set in the background. By subsetting \"subparts\", the parts of the eVehicle get a generic type \"Part\" from the SysML v2 library."

    "\n",
    "When modeling variability with SysML v1, the model can easily explode, i.e., a small variability can lead to the need to model many model elements. I change a bit the structure of the vehicle, for example, I define the wheels as parts of the axis. I also remove the part definition Wheel and define a some lug bolts of the wheels. Finally, we have a deep nested structure: eVehicle owns axis owns wheel owns lug bolt."
