CHAPTER Customizing SysML for Specific Domains 15 This chapter describes how to customize SysML using profiles and model libraries. These types of customization support a wide range of domains that systems modeling can be applied to. This chapter also addresses a number of advanced metamodeling concepts that are typically of interest to language designers, and others who may be responsible for customizing the language to meet domain-specific needs. 15.1 OVERVIEW SysML is a general-purpose systems modeling language that is intended to support a wide range of domain-specific applications such as the modeling of automotive or aerospace systems. SysML has been designed to enable extensions that support these specialized domains. An example may be
