A list of data frame(s) with madshapR::class 'taxonomy'.
A taxonomy is a classification schema that can be defined for variable

Opal environment, and a
taxonomy object is a data frame that must contain at least the columns
taxonomy, vocabulary, and terms. Additional details about Opal
taxonomies are
available online.
