ChronometricAge

http://rs.tdwg.org/chrono/terms/ChronometricAge

Extension to Occurrence Core to capture chronometric age information to be used only in cases where the collecting event is not contemporaneous with the time when the dwc:Organism was alive in its context. Collection event information can be reported in dwc:eventDate. See also the normative term list document at https://tdwg.github.io/chrono/list/ and the human-friendly Quick Reference Guide at https://tdwg.github.io/chrono/terms/.

Keywords: dwc:Occurrence
