ISOyear

This function returns year part of date string.

Usage:
{{#invoke:ISOdate|ISOyear|target_string}}

Parameters
1: The date string

Error Handling:
If the string does not look like it contain the year than the function will not return anything.
That is the preferred treatment for the template:Creator which is the main (only?) template calling it.

ISOdate

This function is the core part of the ISOdate template.

Usage:
{{#invoke:ISOdate|ISOdate|target_string|lang=}}

Parameters:
1: The date string
lang: The language to display it in
form: Language format (genitive, etc.) for some languages
class: CSS class for the <time> node

Error Handling:
If the string does not look like it contain the proper ISO date than the function will return the original string.

That is the preferred treatment for the template:Information (and similar templates) which calling it.
