collecting event: When and where an effort was made to collect. Events should include all of the species that were collected at the same place and time.
collection object: A phyiscal specimen held in a museum or collection. Specimens may be whole or partial animals. Specimen occurrences are thus verifiable in ways that other occurrence are not since the specimen and original labels are usually available for examination.
georeference (georeferencing): A georeference defines a location in terms that a computer can easily understand. As implemented in this project, it includes a point (as latitude and longitude coordinates) and a spatial error (radius in meters). Georeferencing is the act of translating textual locality descriptions into points and radii.
occurrence: When and where a collection object was collected. An occurrence is defined by at least three critical pieces of information; date, location, and taxonomic determination.
