Hi Jeff, Tom,

my first idea about this was not technical at all. Even if you have only a sheet of paper with an overview, which properties are used, and about possible restrictions (mandatory, cardinality, etc) imposed on the data in the source (legacy) sytstems, this can be extremely helpful for dealing with the data. 

More real and formally validatable control is better, of cause. And as the text is phrased now, it gives the hints to the general idea, and to a formal implementation in the Singapore Framework as well (where the reader can buy in or not). 

Cheers, Joachim
