Figures 3 and 5 are confusing and will lead to mis-implementations and frustration. Would like to flatten them some what if it is at all possible. a. Put more in Common properties at same level b. Why do we have to cluster descriptive and computable findings in distinct objects? Their computability will be obvious from the data type. There are few descriptive observations and building structure to distinguish them adds to the complexity c. ISCN is just another variable and shouldn't need the complex structure to carry it. d. Recognize that complex variants could also be haplotypes any way to merge them another
