The Tree Ring Data Standard (TRiDaS) is described in Jansma et. al (2010).
The function has four usage modes:
When idx is given, returns item number
idx in the given category. There may be
several numbers in idx, in which case multiple items
are returned.
When term contains one or more items and
match.exact is TRUE, checks whether any of the
terms is an exact match in the given category
When term contains one or more items and
match.exact is FALSE, expands partial matches of
the terms in the vocabulary of the given category
When only category is given, returns the complete
vocabulary in the given category
