<div>I have made something that uses the geo vocabulary but also
allows pointRadiusSpatial fit measure that I call radius.</div>
<div><br>
</div>
<div>The advantage is that this adds a standard way to deal use
something like an extent or pointRadiusSpatial while still benefiting
from the widely used geo vocabulary.</div>
<div><br>
</div>
<div>It also allows these "Areas" to be referenced in a commonly
understood urn way that using a ietf standard.</div>

<div>For example: "<span style="font-family:tahoma,sans-serif;font-size:13px;border-collapse:collapse">geo:44.86528100,-87.23147800;u=10"</span></div>

</div>
<div>There are still some things I need to fix and check with this
vocabulary but I am wondering if there is any interest in incorporating
this into the DarwinCore.</div>
<div><br>
</div>
<div>If not I will probably change the name of the ontology.</div>
<div><br>

<div>There are also things in the example below that are not part of
my proposal.</div>

<div><br>
</div>
<div>The predicates are a bit awkward, but I wanted to be clear that
this was to link an "Area" like <span style="font-family:tahoma,sans-serif;font-size:13px;border-collapse:collapse">"geo:44.86528100,-87.23147800;u=10" </span>to
a Geonames "Feature".</div>
<div><br>
</div>
<div>I thought a different set of predicates could be created to deal
with some other class of "SpatialThing" if needed.</div>
