This wiki page might be relevant:

https://github.com/okfn/ckan/wiki/Converters-and-Validators-in-navl-Schemas

The validators are called by the validate() function (in
ckan/lib/navl/dictization_functions.py). Each action function in
ckan/logic/action/*.py should call validate() at some point, passing in
the appropriate schema.
