I don't know about reading but a good skim of /Temporal Data and the Relational Model/ by Date, Darwen and Lorentzos might get some juices flowing. And if I recall correctly Fabian may have had a word or two to say in /Practical Issues.../ Frankly, I don't know whether anyone else has even looked at 6NF.

6NF has apparent utility for temporal data, and I think it seems to have utility for partially known data. At the same time, current syntaxes seem a little awkward when working with 6NF. The question is: What short-hands would facilitate working with 6NF data? What is the significance, if any, of those short-hands?
