Parcellation TermSet vs Parcellation Terminology?

[carolth]

Hi, i am not understanding the difference between a Parcellation TermSet and a Parcellation Terminology. Do you have an example to highlight the individual meanings of these classes?

The anatomical structure model has the following:

ParcellationTerminology:
is_a: VersionedNamedThing
description: >-
A parcellation terminology is a versioned release set of terms that can be used to label
annotations in an atlas, providing human readability and context and allowing communication
about brain locations and structural properties. Typically, a terminology is a set of
descriptive anatomical terms following a specific naming convention and/or approach to
organization scheme. The terminology may be a flat list of controlled vocabulary, a taxonomy
and partonomy, or an ontology (ref: ILX:0777107, RRID:SCR_023499)

ParcellationTermSet:
is_a: VersionedNamedThing
description: >-
A parcellation term set is the set of parcellation terms within a specific parcellation terminology.
A parcellation term set belongs to one and only one parcellation terminology and each parcellation
term in a parcellation terminology belongs to one and only one term set.
If the parcellation terminology is a taxonomy, parcellation term sets can be used to represent
taxonomic ranks. For consistency, if the terminology does not have the notion of taxonomic ranks,
all terms are grouped into a single parcellation term set.
