.SH "DESCRIPTION"
.IX Header "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.
.SS "Additional Method"
.IX Subsection "Additional Method"
.IP "\(bu" 4
\&\f(CW\*(C`to_kml\*(C'\fR
.Sp
This method exports the geo object as \s-1KML.\s0 It requires RDF::KML::Exporter to work,
and will throw an error at run-time if it's not available.
.SH "MICROFORMAT"
.IX Header "MICROFORMAT"
HTML::Microformats::Format::geo supports geo as described at
<http://microformats.org/wiki/geo>, with the following additions:
.IP "\(bu" 4
\&'altitude' property
.Sp
You may provide an altitude as either a number (taken to be metres above sea level)
or an embedded hMeasure. e.g.:
.Sp
.Vb 5
\& <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>

\&'body' and 'reference\-frame'
.Sp
The geo microformat is normally only defined for \s-1WGS84\s0 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.
.SH "RDF OUTPUT"
.IX Header "RDF OUTPUT"
Data is returned using the W3C's vCard vocabulary
(<http://www.w3.org/2006/vcard/ns#>) and the W3C's 
\&\s-1WGS84\s0 vocabulary (<http://www.w3.org/2003/01/geo/wgs84_pos#>).
.PP
For non\-WGS84 co-ordinates, \s-1UNGEO\s0 (<http://buzzword.org.uk/rdf/ungeo#>)
is used instead.
