name - this should be the name (or one of the names) as given in the CRHP for the site. It may contain links.
coordname - this is a plaintext name that will be used in mapping the site. It may not contain links or other wiki markup. Note: if "lat/lon" are used and the "name" contains links then "coordname" must be used to avoid problems with the coordinates display.
region - one of the two letter provincial/territorial codes.
address - the street address, or other description of the site's location with the community. Ideally this parameter will include the use of {{sort}} so that the entries in a table will sort well by this parameter. If blank, will use the Wikidata property
located at street address or
location.
idf - a federal designation number in the CRHP; the template will provide a link to the CRHP using this number.
idf2 - a second federal designation number in the CRHP for sites registered twice at the federal level (used for national historic sites and historic railways); the template will provide a link to the CRHP using this number.
idp - a provincial designation number in the CRHP; the template will provide a link to the CRHP using this number.
idm - a municipal designation number in the CRHP; the template will provide a link to the CRHP using this number.
The HTML markup produced by this template includes an
hCard microformat, which makes the place-name and location
parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to an address book. Within the hCard is a
Geo microformat, which additionally makes the
coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a
GPS unit. For more information about the use of
microformats on Wikipedia, please see
the microformat project.
