  Ensuring and validating the safe operation of automated vehicles are key
challenges for their market launch. Scenario-based development and test
approaches are currently being pursued as possible solutions. An essential
prerequisite for researching, applying, and standardizing these approaches is a
consistent and agreed-upon taxonomy. This taxonomy must include relevant terms,
their description, and the relationships between the respective terms. To the
best of our knowledge, such a taxonomy does not yet exist, which often leads to
misunderstandings, for example, in coordination processes and discussions. This
publication contributes to this taxonomy. For this purpose, we propose a
framework for structuring the taxonomy. Within this framework, we propose a
basic vocabulary by identifying and describing terms that we consider
particularly relevant for an overview of such scenario-based development and
test approaches. Additionally, we visualize the proposed terms and the
relationships between these terms with UML diagrams and explain the application
of the proposed basic vocabulary with an example.
