testValid: Validate a DDI element.

In DDIwR: DDI with R

Validate a DDI element.

Description

Attempts a minimal validation of a DDI Codebook element, by searching for mandatory elements and attributes.

Usage

testValid(element, monolang = TRUE)

Arguments

element	A standard element of class "DDI".
monolang	Logical, the codebook file is monolingual

Details

This function currently attempts a minimal check for the absolute most mandatory elements, such as the stdyDscr. An absolute bare version of this element, filled with arbitrary default values, can be produced with the function makeElement(), activating its attribute fill. It also checks for chained expectations, that is element X is mandatory only if the parent element is present.

Future versions will implement more functionality for recommended elements and attributes, with the intention to provide a 1:1 validation as offered by the "CESSDA Metadata Validator".

To ease the validation of the DDI Codebook XML files, the argument monolang is activated by default. This means a single attribute xmlang in the main codeBook element. For multi-language codebooks, an error is flagged if this argument is missing where appropriate.

Value

A character vector of validation problems found.
