Optional checks to consistency of metadata
Description
These functions check to see if values (e.g labels, formats) that should be consistent for a variable across all data are actually consistent.

Verify that the Class Type of an object is DatasetMeta with warnings
Description
This function that is a wrapper to the functions is_metacore and
is_DatasetMeta.
This function is not intended to be called directly by the user. It is
used as a guard clause in many features of the {metatools} package that are
intended only to be used with the subsetted Metacore object of class type
DatasetMeta. If either of the wrapped functions return FALSE then
execution is stopped and an appropriate error message is displayed.
Usage

Arguments
metacore |
An object whose class type needs to be checked. |
Value
Logical: TRUE if the class type of metacore is DatasetMeta,
otherwise abort with errors.
