Phillip,
I noticed in both your and KUMC's ontology with RXNORM, there are no leaf nodes, or should I say, what I think of as leaf nodes are labled FA - so Folders. Once you get down to the MED_ID in KUMC's case, and the RXCUI in UTSW's case, why do you still have it as a Folder instead of a LA - leaf? --- Debbie Yoshihara University of Wisconsin
