What is Capella?

Capella is the Model-Driven Engineering (MDE) solution provided by Thales. It is a Tooled-Up-Process solution that enacts Systems Engineering and Software Architecture Engineering recommendations defined by Arcadia, the Thales standard Systems Engineering Method that promotes functional analysis and early validation.

For more information on Arcadia, please refer to the dedicated page on the website and check out the introduction document.

Capella has been specified, designed and developed for providing a high value engineering environment to the System Engineering and Software Architecting teams, promoting innovative approaches in engineering practices. It benefits from the return on experiment from previous deployment of MDE in Thales large projects and from recent progress in the MDE technology domain. It has been successfully deployed in a wide variety of industrial contexts and proved to have an acceptable maturity for deployment in terms of reliability, robustness, performance, efficiency and adaptability.

Capella provides its integrated tooled-up process solution on top of the state-of-the-art de facto standard Eclipse Open Source IDE Platform.

Capella is based on PolarSys solution and Eclipse components, notably:

  • Kitalpha and its Core Technology Kit, that provides the architectural foundations of Capella and which is the Capella viewpoint development and runtime environment ;
  • Sirius, used at development time (e.g., for a graphical rendering of the architectures) and runtime (e.g., for architectures edition through diagrams and tables) ;
  • EMF Diff/Merge that provides Capella advanced model tooling capabilities (e.g. model diff/merge, iterative transformations, pattern support, etc.) ,
  • EGF used for producing and maintaining the Capella metamodels, helpers.
