Well, as a hierarchical or relational database, the primary information 
needed is the key blank, and the numbers of the cuts, such as SC1 7 4 1 3 

(Some manufacturers have "rules" that I'm not familiar with, such as 
"never put a cut deeper than 5 next to a cut shallower than 2", "never use 
a cut deeper than 7 as the cut nearest the bow, or it may break!", and 
some will always use even number depths on some cuts and odd numbers on 
others. Such rules are necessary in designing a new key, but irrelevant 
for making a duplicate or replacement)

At an additional level in the database, or separate databases, would be 
the depth and spacing data for that blank and/or that usage of that blank, 
specifically, the spacing from the bow (or tip in a few exceptions) and 
the depths of the various standard cuts.

Further, a comprehensive database for machinists could lay out what the 
milling is to be for each blank.  Key blank availability tends to be good 
enough that that information would rarely be needed.
