Yes, you can extend the SCA meta model to include additional elements on
components, services and references. You can also add a property tab
displaying those elements (not a widget on the graphical representation).
There is a sample on the svn . This sample provides an extension 
to add SAWSDL annotations on SCA elements. Have a look to the following
plugins: org.eclipse.stp.sca.semantic.sawsdl and
To implement your own extension:
- First, create an ecore model describing your extension and generate
the code. Your elements must extend the EClass named AnyExtension
(defined in the SCA meta model). You must also add an element that
extends DocumentRoot. Have a look to the SAWSDL meta model defined in
- Then, create a class that extends IFilter and a class that extends
ScaPropertySectionProvider. Define also the extensions needed. Have a
look to org.eclipse.stp.sca.semantic.sawsdl.edit/customsrc and to plugin.xml
Currently, this extension mechanism is only available with the OSOA meta
model (not with the OASIS one).
