I have successfully created the Eclipse Plugin from the downloaded ISO20022 ecore implementation metamodel as described: https://www.iso20022.org/iso20022-repository/e-repository
Under the Repository I can see the Data Dictionary and Business Process Catalogue. I can view and modify the Data Dictionary Message Components. However when I view the Message Definitions (under Business Process Catalogue) - I can't see how their definitions relate to the Message Components - I would expect the Toplevel Message / Body to link to the Data Dictionary. (That is the whole point after all: https://www.iso20022.org/understanding-data-dictionary) Is there something I am missing here?
