It also defines typegroup memberships of the types within specific schemes,
The codes of schemes and types (and optionally: typegroups)
are explained in the

A vc-formatted data source. As such, it corresponds to a dataframe with 3 variables:
An optional code (and optionally explained by
declaring the typegroup to which a type belongs within the specified
Typegroups point out which types are considered together as a group in
inferences for the scheme at hand.
Each combination of
type must be unique.
For the MNE-schemes:
the link between schemes and types comes from
a vc-formatted, Dutch-language data source
which can be found in the
n2khab Github repository:
This data source was originally generated in the
the declaration of typegroups comes from this googlesheet. Currently, the typegroups are kept up to date both in the googlesheet and in the data source.
For the MHQ-schemes, the list of sampled types is based on the report of Westra et al. (2014).
