[Vp-integration-subgroup] About taxonomies

Tue May 18 16:16:09 PDT 2021

Actually John,

There are taxonomies in some fields. Here is an older paper:
http://www.medicine.mcgill.ca/epidemiology/courses/EPIB654/Summer2010/Modeling/Brennan2006.pdf

Perhaps its time to renew it and add newer techniques and extend it to more
fields, yet taxonomies do exist.
