[tdwg-content] Proposal to Add a GeoSpatial "Area" to the DarwinCore

[Peter DeVries]

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: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.

Respectfully,
