I wrote about this earlier but I never heard anything back.
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:title44.86528100, -87.23147800 Radius 10 meters</dcterms:title> <dcterms:isPartOf rdf:resource="http://lod.taxonconcept.org/ontology/void#this%22/%3E dcterms:identifiergeo:44.86528100,-87.23147800;u=10</dcterms:identifier> dcterms:created2010-10-28T00:00:00-0500</dcterms:created> dcterms:modified2010-11-09T16:33:34-0600</dcterms:modified> geo:lat44.86528100</geo:lat> geo:long-87.23147800</geo:long> <dwc_area:radius>10</dwc_area:radius> txn:elevation186.54</txn:elevation> txn:continentNorth America</txn:continent> txn:countryCodeUS</txn:countryCode> txn:countryUnited States</txn:country> txn:stateProvinceWisconsin</txn:stateProvince> txn:countyDoor</txn:county> txn:localityTextTown of Sevastopol</txn:localityText> txn:locationNameShivering Sands Natural Area Woods</txn:locationName> <txn:areaHasOccurrence rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9#Occurre... <txn:areaHasObservedSpeciesConcept rdf:resource="http://lod.taxonconcept.org/ses/ICmLC#Species%22/%3E <txn:areaHasIndividual rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9#Individ... <txn:areaInStateProvince rdf:resource="http://sws.geonames.org/5279468/%22/%3E <txn:areaInCounty rdf:resource="http://sws.geonames.org/5250768/%22/%3E <wdrs:describedBy rdf:resource="http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9.rdf%22/... </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.
