I have made something that uses the geo vocabulary but also allows pointRadiusSpatial fit measure that I call radius.

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.

It also allows these "Areas" to be referenced in a commonly understood urn way that using a ietf standard.

For example: "geo:44.86528100,-87.23147800;u=10"

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.

If not I will probably change the name of the ontology.

There are also things in the example below that are not part of my proposal.

I have what I call "Areas" that look like this:

<dwc_area:Area rdf:about="geo:44.86528100,-87.23147800;u=10">

<dcterms:title>44.86528100, -87.23147800 Radius 10 meters</dcterms:title>

<dcterms:isPartOf rdf:resource="http://lod.taxonconcept.org/ontology/void#this"/>

<dcterms:identifier>geo:44.86528100,-87.23147800;u=10</dcterms:identifier>

<dcterms:created>2010-10-28T00:00:00-0500</dcterms:created>

<dcterms:modified>2010-11-09T16:33:34-0600</dcterms:modified>

<geo:lat>44.86528100</geo:lat>

<geo:long>-87.23147800</geo:long>

<dwc_area:radius>10</dwc_area:radius>

<txn:elevation>186.54</txn:elevation>

<txn:continent>North America</txn:continent>

<txn:countryCode>US</txn:countryCode>

<txn:country>United States</txn:country>

<txn:stateProvince>Wisconsin</txn:stateProvince>

<txn:county>Door</txn:county>

<txn:localityText>Town of Sevastopol</txn:localityText>

<txn:locationName>Shivering Sands Natural Area Woods</txn:locationName>

<txn:areaHasOccurrence rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9#Occurrence"/>

<txn:areaHasObservedSpeciesConcept rdf:resource="http://lod.taxonconcept.org/ses/ICmLC#Species"/>

<txn:areaHasIndividual rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9#Individual"/>

<txn:areaInStateProvince rdf:resource="http://sws.geonames.org/5279468/"/>

<txn:areaInCounty rdf:resource="http://sws.geonames.org/5250768/"/>

<wdrs:describedBy rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9.rdf"/>

</dwc_area:Area>

I recently added the following predicates, but have not altered my RDF examples.

#featureContainsArea

#areaWithInFeature

http://lod.taxonconcept.org/ontology/dwc_area.owl

OWL Doc http://lod.taxonconcept.org/ontology/dwc_area_doc/index.html

The predicates are a bit awkward, but I wanted to be clear that this was to link an "Area" like "geo:44.86528100,-87.23147800;u=10" to a Geonames "Feature".

I thought a different set of predicates could be created to deal with some other class of "SpatialThing" if needed.
