Tests if an object is a valid DataSchema object with specific format restrictions for compatibility with other Maelstrom Research software. This function mainly helps validate input within other functions of the package but could be used to check if an object is valid for use in a function.

is_dataschema_mlstr(object)

Arguments

object

A potential DataSchema object to be evaluated.

Value

A logical.

Details

A DataSchema is the list of core variables to generate across datasets and related metadata. A DataSchema object is a list of data frames with elements named 'Variables' (required) and 'Categories' (if any). The 'Variables' element must contain at least the name column, and the 'Categories' element must contain at least the variable and name columns to be usable in any function. In 'Variables' the name column must also have unique entries, and in 'Categories' the combination of variable and name columns must also be unique.

The object may be specifically formatted to be compatible with additional Maelstrom Research software, in particular Opal environments.
