My intention at the time I wrote http://www.openhealth.org/RDDL/SchemaAlgebra was to _start_ to write down some of these definitions in as precise a fashion as possible, but frankly I've not edited it in awhile. I also don't mean to dictate (as if I alone _could_) that these actually be the definitions written in stone, rather to propose some precise definitions that can be discussed if others agree. In any case RF has said much the same as I had proposed and I suspect that he arrived at his impressions entirely independently of my referenced document -- I haven't scoured the details of his thesis to see if similar equations are contained within -- but this does suggest that we might have something concrete to discuss as part of a Web Architecture document.
