Hi,
I was trying to come up with a way to represent location with different markup
solutions.
# Simple HTML
<ul id="places">
<li>Montréal, Canada</li>
<li>Paris, France</li>
</ul>
# Using dataset (can be queried with dataset API)
<ul data-georef="WGS84" id="places-ds">
<li><span
data-geolat="45.5"
data-geolon="-73.666667">Montréal</span>, Canada</li>
<li><span
data-geolat="48.856578"
data-geolon="2.351828">Paris</span>, France</li>
</ul>
* Issue: These data are not referring to any vocabulary agreement, they are
really meant to be private to the page. So really not the best use of dataset.
# Using microdata (can be queried with microdata API)
<ul id="places-md"
itemprop="geo"
itemscope
itemtype="http://data-vocabulary.org/Geo";>
<li>
<span class="city">
<meta itemprop="latitude" content="45.5" />
<meta itemprop="longitude" content="-73.666667" />
Montréal</span>, Canada</li>
<li>
<span class="city">
<meta itemprop="latitude" content="48.856578" />
<meta itemprop="longitude" content="2.351828" />
Paris</span>, France</li>
</ul>
* Issue: Doesn't define the reference system which has been used
http://www.data-vocabulary.org/Geo/
* Issue: Verbose
# Using RDFa (not implemented in browsers)
<ul xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#"; id="places-rdfa">
<li><span
about="http://www.dbpedia.org/resource/Montreal";
geo:lat_long="45.5,-73.666667">Montréal</span>, Canada</li>
<li><span
about="http://www.dbpedia.org/resource/Paris";
geo:lat_long="48.856578,2.351828">Paris</span>, France</li>
</ul>
* Issue: Latitude and Longitude not separated
(have to parse them with regex in JS)
* Issue: xmlns with <!doctype html>
# Question
On RDFa vocabulary, I would really like a solution with geo:lat and geo:long,
Ideas?
