What is a Data Page?

Suppose a page named "XYZ" contains the following wikitext:

{{{{{format|DefaultTemplate}}}
|param1=abc
|foo=bar
|some.property=some value
|empty_value=
|{{{1|}}}
}}

Any page that contains code like this is a data page. A data page cannot render itself, but instead feeds its parameters to a rendering template ("DefaultTemplate" in this example) which is responsible for rendering the page.

(Note: The markup above must be wrapped in a <onlyinclude></onlyinclude> tag.)

The Template:Data template can extract individual fields from a data page, like this:

Wiki markup Result
{{data|XYZ|param1}}
abc
{{data|XYZ|foo}}
bar
{{data|XYZ|some.property}}
some value
{{data|XYZ|empty_value}}
{{data|XYZ|empty_value|default value}}
default value
{{data|XYZ|value that does not exist|default value}}
default value
