NAME

HTML::Microformats::Format::geo - the geo microformat

SYNOPSIS

 use Data::Dumper;
 use HTML::Microformats::DocumentContext;
 use HTML::Microformats::Format::geo;

 my $context = HTML::Microformats::DocumentContext->new($dom, $uri);
 my @geos    = HTML::Microformats::Format::geo->extract_all(
                   $dom->documentElement, $context);
 foreach my $geo (@geos)
 {
   printf("%s;%s\n", $geo->get_latitude, $geo->get_longitude);
 }

DESCRIPTION

HTML::Microformats::Format::geo inherits from HTML::Microformats::Format. See the base class definition for a description of property getter/setter methods, constructors, etc.

Additional Method

  • to_kml

    This method exports the geo object as KML. It requires RDF::KML::Exporter to work, and will throw an error at run-time if it's not available.

MICROFORMAT

HTML::Microformats::Format::geo supports geo as described at http://microformats.org/wiki/geo, with the following additions:

  • 'altitude' property

    You may provide an altitude as either a number (taken to be metres above sea level) or an embedded hMeasure. e.g.:

     <span class="geo">
      lat:  <span class="latitude">12.34</span>,
      long: <span class="longitude">56.78</span>,
      alt:  <span class="altitude">90</span> metres.
     </span>
     
     <span class="geo">
      lat:  <span class="latitude">12.34</span>,
      long: <span class="longitude">56.78</span>,
      alt:  <span class="altitude hmeasure">
              <span class="num">90</span>
              <span class="unit">m</span>
            </span>.
     </span>
  • 'body' and 'reference-frame'

    The geo microformat is normally only defined for WGS84 co-ordinates on Earth. Using 'body' and 'reference-frame' properties (each of which take string values), you may give co-ordinates on other planets, asteroids, moons, etc; or on Earth but using a non-WGS84 system.

RDF OUTPUT

Data is returned using the W3C's vCard vocabulary (http://www.w3.org/2006/vcard/ns#) and the W3C's WGS84 vocabulary (http://www.w3.org/2003/01/geo/wgs84_pos#).

For non-WGS84 co-ordinates, UNGEO (http://buzzword.org.uk/rdf/ungeo#) is used instead.

BUGS
