The extension TemplateData introduces a <templatedata> tag and an API which together allow editors to specify how templates should be invoked.

Not all data types that can be selected for a parameter, have any actual effect and are treated as "unknown":

Value	Description
unknown	standard setting no visible effect
string	intended for any string of plain text no visible effect
line	intended for content that should be forced to stay on one line Effect:"line" prevents a parameter's input box from allowing new lines
content	The "content" value is intended for wikitext of page content, for example, links, images or text formatting. no visible effect
unbalanced-wikitext	intended for wikitext that cannot stand alone, i.e. it lacks an opening or closing tag or refers to other parts of wikitext. no visible effect
wiki-page-name	intended for a page name on a wiki Effect: Shows a suggestion dropdown menu containing a list of pages on the wiki, which can be selected. Namespaces can also be defined in the search. Additionally, it forces the input box content to stay on one line. It doesn't prevent a non-page from being inputted.
wiki-file-name	intended for a locally hosted file name no visible effect
wiki-template-name	intended for the name of a template Effect: Shows a suggestion dropdown menu containing a list of templates, which can be selected. Additionally, it forces the input box content to stay on one line. It doesn't prevent a non-template from being inputted.
wiki-user-name	intended for a username on a wiki Effect: Shows a suggestion dropdown menu containing a list of actual users' names, which can be selected. Additionally, it forces the input box content to stay on one line. It doesn't prevent a non-username from being inputted.
number	intended for numerical values, including negative values and decimals. no visible effect
boolean	intended for a value that is either true, false or unknown. This is intended by the manual to be represented by a "1", "0" or blank value. Effect: With the autovalue:0, a checkbox appears in the visual editor, which can be switched on and off.
date	intended for a date in the YYYY-MM-DD format no visible effect
url	intended for a URL, with Internet protocol (e.g., "https://" or "//") included Effect: It makes the input box display an external link icon (a square with arrow pointing out of it) in the left hand side of the box and makes the box glow red when the user clicks away without entering a URL value that includes a valid Internet protocol (e.g., "https://", "ftp://" or "//") followed by some text.
