Capella 1.1.0

Primary tabs


Capella 1.1.0 is a major release:

  • 97 bugs have been fixed
  • 44 evolutions have been implemented

These corrections involve:

  • REC-RPL mechanism
  • The Core of Capella
  • Library management
  • Documentation
  • Diagram management
  • Transition system
  • Model Validation
  • Capella user interface
  • Diff-Merge component adaptation
API Certification: 

The project leadership certifies that the APIs in this release are "Eclipse Quality".

Architectural Issues: 

There is no specific issue detected on the Capella solution architecture.
Capella is a modular platform which uses Eclipse modeling components, Sirius and EMF Diff/Merge, and a PolarSys component, Kitalpha.
The role of Kitalpha is twofold:

  • Providing basic components from the Kitalpha Core Technology Kit (e.g. Transposer)
  • Extending Capella with Viewpoints for System co-engineering

Some components from Capella were externalized as new components on Amalgam project in order to be reusable (Activity Explorer, Contextual Explorer).

Security Issues: 

There is no specific security issue detected on the Capella solution.

Non-Code Aspects: 

All communication links regarding Capella solution are up-to-date:

  • Wiki with "News" section
  • Website with different sections:
    • Installation instructions on Getting Started page
    • Community links
    • Download page for Capella and Documentation
    • Events around Capella solution (conferences, talks, etc.)
    • Links to YouTube dedicated channel for Capella as well as LinkedIn page and Twitter
  • Forum
  • Project page
  • In-Flight Entertainment and Alarm Clock samples
  • Bugzilla, Hudson instance
  • Twitter and LinkedIn pages
  • Wikipedia dedicated page in FR and EN languages
Usability Details: 

Capella solution UI is compliant with User Interface Guidelines.
The workbench is decomposed as shown in the Wiki figure:

  • On the left, the Capella "model" project explorer
  • In the center, the Overview for Arcadia phases and Diagrams editors
  • Property views and Semantic browser at the bottom
  • Fast linker (optional) in the bottom left-hand corner providing facilities for diagrams edition
End of Life: 

No APIs and significant features are intended to be deprecated in a near future.
Improvements next year (2017) on Capella solution feature:

  • Performance increase
  • Ergonomics
  • Fix bugs
  • Viewpoints
  • Connectors to other tools

Capella solution implement the Arcadia model-based engineering method for systems, hardware and software architectural design.
Before Arcadia is officially and entirely published, a light introduction explaining the rationale and main concepts is now available for download on the website.

Also, a dedicated page on Wikipedia has been written.
