Sirius editors inherit from
org.eclipse.sirius.ui.business.api.dialect.DialectEditor.
If your active editor is a DialectEditor, you will have access to the
getDRepresentation() method, then you could check if it is a
org.eclipse.sirius.viewpoint.DSemanticDecorator (all current Sirius
concrete representations (diagram, table, tree) inherit from it as the
representation elements).
This DSemanticDecorator interface has a getTarget() method which will
return the represented semantic object.
For a representation (diagram, table, tree), it will be the semantic
element on which the user created it.
Then if you want its semantic resource, just call eResource() on it.

Sirius is able to deal with several semantic resource, there is no
"main" semantic resources except if your are not using the modeling
project nature, in this legacy mode, the first semantic resource should
be the one on/from which your created the aird file.

This indeed gives me the right direction. Thanks a lot.
For those who are also interested in this issue and want to edit the semantic element, use the following code:
EObjectQuery query = new EObjectQuery(target);
Session session = query.getSession();
final ModelAccessor accessor = session.getModelAccessor();
TransactionalEditingDomain ted = session.getTransactionalEditingDomain();
ted.getCommandStack().execute(new RecordingCommand(ted) {
@Override
protected void doExecute() {
...
}
});
