Dear all,

On 13 October the Executive Committee approved the recommended changes to
the Darwin Core associated with species establishment. As of 21 October the
Darwin Core standard and associated documentation (including the Quick
Reference Guide - https://dwc.tdwg.org/terms/) have been updated to
dwc:degreeOfEstablishment (
https://dwc.tdwg.org/terms/#dwc:degreeOfEstablishment) (new, with
controlled vocabulary)
dwc:pathway (https://dwc.tdwg.org/terms/#dwc:pathway) (new, with controlled
dwc:establishmentMeans (https://dwc.tdwg.org/terms/#dwc:establishmentMeans)
(change in definition, with controlled vocabulary)

as well as the IRI versions of these same terms in the dwciri: namespace
for use in RDF.

Utility files with the horizontal (1 row) and vertical (1 column) term name
lists can be found and downloaded from the DarwinCore Github site at

Enjoy the richer capacity to share species establishment information!

John (on behalf of the Darwin Core Maintenance Interest Group)
