OMG - Domain-Specific Modeling with SysML v2 (by Ed Seidewitz)

  • A general-purpose modeling language(GPML) is broadly applicable for all kinds of modeling.
  • A domain-specific modeling language(DSML) is specialized to a specific application domain (e.g., aerospace, automotive, etc.), engineering domain(e.g., control, electrical, earodynamtics, etc.) or other purpose(e.g., supporting specific organizational processes).

Domain-specific modeling is (1) systematically using DSMLs to model various facets of a system… or (2)…systematically adapting a GPML to model different domains.SysML is a GPML for systems modeling.（SysML是后者）

SysML v1 was typically adapted for domain-specific modeling using profiles.(Stereotypes adapt specific SysML v1 elements for domain-specific concepts. Tools can key off stereotypes to provide domain-specifc visualization, validation, etc.) SysML v1 was itself defined as a profile of UML. However, stereotypes provide only a syntactic marker, with no formal specification of semantics.（是否可以理解成：SysML v1基于UML开发，只提供了一个框架，没规范语义细节）

  • SysML v2 is a general-purpose modeling language with powerful capabilities for domain-specific modeling.
  • SysML v2 concepts of concepts of metadata and model libraries replace the v1 concepts of stereotypes and profiles,
    • Model libraries to define domain-specific semantics.
    • Metadata to annotate user model elements and tie them to semantic library base types.
  • Already being used for standard domain-specific language specification.
  • Allow domain-specific modeling at project, organization and community levels.
