Darwin Core Archive Format


The Core Taxon File


Repository URL: http://rs.gbif.org/core/dwc_taxon.xml


Field Description
taxonID A ‘taxonID’ value may be any string, it is not required to be numeric.

An accepted name should have a unique ‘taxonID’ value. A synonym (or similar name linked to a taxon) should ideally have an identifier in the ‘taxonID’ field.

Qualified Name: http://rs.tdwg.org/dwc/terms/taxonID

Data Type: string

acceptedNameUsageID The field ‘acceptedNameUsageID’ should be used to link a synonym record to its corresponding accepted name (which will have a matching ‘taxonID’ value).

An accepted name should have an empty ‘acceptedNameUsageID’ field.


Qualified Name: http://rs.tdwg.org/dwc/terms/acceptedNameUsageID

Data Type: string

parentNameUsageID The field ‘parentNameUsageID’ of the accepted name record for a taxon is used to refer to the ‘taxonID’ value of the parent taxon at the next higher taxonomic rank included in the checklist.

If there is no parent included in the checklist, because the “top of the tree” has been reached, then this field should be empty to indicate this.

Qualified Name: http://rs.tdwg.org/dwc/terms/parentNameUsageID

Data Type: string

scientificName The scientific name of taxon with or without authorship information

depending on the format of the source database.


Examples: "Coleoptera" , "Vespertilionidae”, "Manis" , "Ctenomys

sociabilis", "Ambystoma tigrinum diaboli", "Quercus agrifolia var.

oxyadenia (Torr.)"


Qualified Name: http://rs.tdwg.org/dwc/terms/scientificName

Data Type: string

scientificNameAuthorship If the authority is known and can be separated from the rest of the scientific name, the authority string should also be placed in the ‘scientificNameAuthorship’ field.

If authorship is included in the scientificName field, this field is

optional.


Example: "(Torr.) J.T. Howell", "(Martinovsk ) Tzvelev", "(Linnaeus

1768)"

Vernacular Names Extension


This extension provides the means to share information related to common (vernacular) names linked to taxa in the core data file. Multiple vernacular names can be linked to the same taxon via the taxonID.


Repository: http://rs.gbif.org/extension/gbif/1.0/vernacular.xml


Field Description
taxonID The first field in the data file should be the taxonID representing the

taxon in the core data file to which this vernacular name points. This

identifier provides the link between the core data record and the

extension record.

Data Type: string

locality The specific description of the area from which the vernacular name

usage originates. Vernacular names may have very specific regional
