The HTML mark up produced by this template includes an hCard microformat, which makes the place-name and location parsable by computers, either acting automatically to catalogue article across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to an address book. For more information about the use of microformats on Wikipedia, please see the microformat project.

If the place or venue has an "established", "founded", "opened" or similar date that is specific to the day, use {{Start date}} unless the date is before 1583 CE. If it has a URL, use {{URL}}.

hCard uses HTML classes including:

  • adr
  • category
  • country-name
  • extended-address
  • fn
  • label
  • locality
  • nickname
  • note
  • org
  • street-address
  • url
  • vcard

Please do not rename or remove these classes nor collapse nested elements which use them.}
