Module:Infobox date field metadata
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This module allows infoboxes using {{Infobox date field metadata}} to automatically produce machine-readable metadata in form of microformats (see also WP Microformats) from infobox fields using recognized dates, times, and date ranges. Unrecognized, ambiguous and incomplete values are skipped and some will produce an error tracking category.
Usage
This module is not intended to be used directly other than from its parent template {{Infobox date field metadata}}. See that template for description.
Parameters
- First paramater is always the input string – this should be the infobox's date field value
|dtstart=yesspecifies that hCalendar (WP:UF#hCalendar)dtstart(event start date) class is to be output if possible|dtend=yesspecifies that hCalendardtend(event end date) class is to be output if possible|trackingCat=yesspecifies that Category:Articles with automatically detected infobox date metadata should be added to every article where metadata was successfully emitted|noErrorCats=yesspecifies that parsing error categories (currently Category:Articles with incomplete date ranges for automatic metadata) should not be added by default
