This presentation introduces basic concepts of categorization in the context of engineering models. Sometimes called ontology, categorization is present in widely-used modeling languages such as the Systems Modeling Language and the Unified Modeling Language (SysML/UML).
It can be used to capture relationships between categories and the things falling into them, including categories of modeling languages elements necessary to define engineering-friendly languages. The presentation introduces basic SysML/UML notation supporting categorization, distinguishing it from sofware modeling uses of these notations.
