Positioning of XMI in V-Model


Reasons for promoting standardization (short list):

  • Enable openness and interoperability for UML/SysML-based modelling tools
  • Exchange information in distributed heterogeneous development environments
  • Enable cooperation across engineering departments and disciplines
  • One single technology standard for connecting tools → no need to develop individual bridges between each pair of tools → more flexibility in choice of tools
  • Take advantage of UML, SysML and XML prevalence in industry
