Property:Has data page

This property identifies the data page that is directly associated with the content page where this property is set. Most infobox templates that query data will set this automatically by setting the name of the page they draw data from here.

Due to caching issues, it may sometimes be necessary to resave a content page to update the property value.

Data page names will usually have a numeric ID in parenthesis at the end of their page name. This is because automatically disambiguating page names the way wiki editors would it is not trivial logic for automated importing tools; the numeric ID makes any name collisions very unlikely.
