统一建模语言(UML,Unified Modeling Language)是由国际软件行业组织 OMG(对象管理集团 omg.org)自 1997 年起研发的用于 IT 各领域建模的一套标准、通用、图形化的面向对象(OO)建模语言,对应的国际标准为 ISO/IEC 19505。UML 具有简单、直观、形象、表达力强等特点,因此不仅常用于复杂软件系统架构的建模和面向对象分析与设计(OOAD),也可用于复杂业务流程及系统需求的建模。UML 当前的最新版本为 v2.5(2015.3)。 UML 起源于 3 位著名的软件工程方法学家 Grady Booch、James Rumbaugh、Ivar Jacobson 融合、统一了他们各自原来的建模语言和方法。

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.
