Editing Template:Death date and age/doc (section)

==Background==
The idea of using the template, as with {{tl|birth date and age}} etc., is to allow for the inclusion of hidden [[metadata]] to be used, indexed or searched by software tools. However, as of October 2008 this template does not include any such metadata and never has since it was founded in December 2006. The apparent reason is that the [[hCard]] [[microformat]], logically enough for an extension of "standard for electronic business cards", contains only "BDAY" field but nothing to do with a death. It is unclear when metadata standard for the dead will be developed and adopted. Until then, the template does nothing but format the input parameters.

Because the hCard specification requires the use of the Gregorian calendar, the template should not be used for dates stated in the Julian calendar.
