Many dbPedia data use geo: namespace: http://www.w3.org/2003/01/geo/wgs84_pos#
For instance the 2600 <http://dbpedia.org/ontology/Garden> . As for tools, my reusable visualizer in a static HTML page detects geo: coordinates: Example view with LeafLet and gardens from a SPARQL query <http://semantic-forms.cc:1952/assets/geo-map/geo-map.html?link-prefix=http://semantic-forms.cc:1952/display?displayuri=&lang=fr&url=http://semantic-forms.cc:1952/sparql?query=%0APREFIX+text%3A+%3Chttp%3A%2F%2Fjena.apache.org%2Ftext%23%3E+%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E+%0APREFIX+form%3A+%3Chttp%3A%2F%2Fraw.githubusercontent.com%2Fjmvanel%2Fsemantic_forms%2Fmaster%2Fvocabulary%2Fforms.owl.ttl%23%3E+%0APREFIX+geo%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2003%2F01%2Fgeo%2Fwgs84_pos%23%3E+%0APREFIX+foaf%3A+%3Chttp%3A%2F%2Fxmlns.com%2Ffoaf%2F0.1%2F%3E+%0ACONSTRUCT+%7B%0A++%3Fthing+geo%3Along+%3FLONG+.%0A++%3Fthing+geo%3Alat+%3FLAT+.%0A++%3Fthing+rdfs%3Alabel+%3FLAB+.%0A++%3Fthing+foaf%3Adepiction+%3FIMG+.%0A%7D+WHERE+%7B%0A++%0A++%0A+graph+%3Fg1+%7B%0A+++%3Fthing+a+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2FGarden%3E+.%0A+%7D+.%0A++graph+%3Fgrll+%7B%0A++++%3Fthing+geo%3Along+%3FLONG+.%0A++++%3Fthing+geo%3Alat+%3FLAT+.%0A++%7D%0A++OPTIONAL+%7B%0A+++graph+%3Fgrlab+%7B%0A++++%3Fthing+rdfs%3Alabel+%3FLAB+%7D+%7D%0A++OPTIONAL+%7B%0A+++graph+%3Fgrlab2+%7B%0A++++%3Fthing+%3Curn%3AdisplayLabel%3E+%3FLAB+%7D+%7D%0A%0A++OPTIONAL+%7B%0A+++graph+%3Fg3+%7B%0A++++%3Fthing+foaf%3Adepiction+%3FIMG+%7D+%7D%0A++OPTIONAL+%7B%0A+++graph+%3Fg4+%7B%0A++++%3Fthing+foaf%3Aimg+%3FIMG+%7D+%7D%0A%0A++++OPTIONAL+%7B%0A+++graph+%3FgrCount+%7B%0A++++%3Fthing+form%3AlinksCount+%3FCOUNT.%0A++%7D+%7D%0A%7D%0AORDER+BY+DESC%28%3FCOUNT%29%0A> . Also the pages and forms in semantic_forms that include geo: coordinates are populated with data coming from GPS: Example, create a botanic observation: https://semantic-forms.cc:1953/create?uri=http%3A%2F%2Fdeductions.github.io%2Fnature_observation.owl.ttl%23Observation Le mer. 12 déc. 2018 à 14:33, Andy Seaborne <[email protected]> a écrit : > Hi Marco, > > Where is' geo' being used? > > Andy > > > On 12/12/2018 12:16, Marco Neumann wrote: > > What do people on the list think about re-using the namespace prefix geo? > > > > it's currently used for > > > > WGS84 Geo Positioning: an RDF vocabulary > > http://www.w3.org/2003/01/geo/wgs84_pos# > > > > but becomes more popular (e.g. see wikidata) as a namespace prefix for > > > > OGC GeoSPARQL 1.0 > > http://www.opengis.net/ont/geosparql# > > > > I would have preferred to see the OGC introduce a new namespace prefix > like > > geosparql but for some reason they settled on replacing geo (W3C ) with > > geosparql (OGC) and geof for functions.
