What would be great is have the possibility to add your own properties (name/value pairs) to a table/field etc. object. For progress I would need properties like column-label and more for the field. I can solve this 'quick and dirty' by editing description fields. My goal is roundtripping; generate a datadefintitionsfile (as I'm not a java programmer that will be written in openedge, the 4GL from progress and extract info from the the erm file) that can be imported in the progress database and the other way around: create/update an xml that can be read by ermaster.
