For example, here is a sparql query that will show the occurrences that are
tagged to the concept for the American Toad.
PREFIX txn: <http://lod.taxonconcept.org/ontology/txn.owl#>
PREFIX american_toad: <http://lod.taxonconcept.org/ses/kQmp4#Species>
DESCRIBE ?x WHERE {
?x txn:occurrenceHasSpeciesConcept american_toad:.
}
This bit.ly link will take you to my endpoint which will display these on a
map. (Need to change the Visualization to GoogleMaps)
http://bit.ly/aHOECG
These should also work on anyone else's endpoint, and on the LOD endpoint
when the set is crawled.
