SCA Composite Tools roadmap

Revision as of 12:29, 26 October 2007 by (Talk | contribs) (Open questions)


  • SCA Composite Metamodel: SCA metamodel (OSOA) + additional binding, interface, implementation (for example Java RMI binding).
  • SCA Composite Designer: GMF modeler.
  • SCA Composite Introspector: Bottom-up approach.
  • SCA Composite Editor: Textual editor for composite files.


  • October 26th 2007: EBM WebSourcing proposes to develop an SCA Composite Editor. This textual editor will provide auto-completion for XML attributes and values according to "known" SCA components.
  • October 2007: End of the IP process.
  • July 20th 2007: Submission of the SCA Composite Designer developed by Obeo as an IP BugZilla.
  • July 5th 2007: SAP and Obeo hosted an open webex demonstration of their respective SCA Composite Designer technologies. SAP and Obeo decided to use as initial contribution the Obeo Composite Designer code.

Current status

End of October 2007

Obeo made several improvements to the code submitted in July (IP BugZilla).

  • Now, the composite files are valid. For example:
    • implementation, binding and interface are correctly generated (,, ...).
    • promote and wire are correctly generated (CompositeName/ComponentName/ServiceName, ...).
    • implementation, interface, binding name are correctly generated (interface=" services.myValue.MyValueService").
  • Moreover, drag and drop works correctly for some implementation, binding, and interface type.

  • Commit of the code submitted as IP bugZilla in July, and then commit of the code developed since July with improvements depicted above. (We can't commit rigth now because we need to get legal sign-off first. Then we will be able to put the code into the contribution directory. Finally, once we have received the community review feedback, we will move the code to its own special CVS directory.)

November2007 - December 2007

  • Implementation of a first version of the bottom-up approach developed by SAP (where the idea is to produce a graphical representation from discovered code composites). Bogdan any precision?
  • Graphical representation of the examples provided by Tuscany. These examples will be used as test cases.
  • Integration of the SCA Composite Editor. It must be synchronized with the SCA Composite Designer.

January 2008

  • Integration with the Policy editor/designer
  • Implementation of the feature "Arrange all".
  • Implementation of additional validation rules. These rules appears in the SCA specification documents but that are not considered by the XSD scheme. We distinguish 2 types of rules:
    • The rules which apply on the SCA assembly description files and
    • The rules which verify coherence between the SCA assembly description files and the implementation.

Open questions

  • How to a add new binding, implementation and interface (extension points)? see [1]
