Darwin Core extension for recording insect observations
This list builds on Darwin Core 2 version 1.30 which has been
documented at http://darwincore.calacademy.org/
This extension offers support for time periods, counts of organisms,
collecting/observing efficiency, and repetition of sites, periods, and
expeditions for large samples. However, this document does not
define data types sites, etc.
This extension does not give full support for linking to other
organisms to express any detail on host-parasite interactions, although
simple strings for these are included.
There also is an element for taxonomic concept identifier and a taxon
numbering system. This is to avoid ambiguity on species that have
been split and lumped. ScientificName simply is not sufficient in
these cases. Because there is often no going back to specimens,
the concept of taxon that was used in identification is needed for
observations mode than it is for specimens.
Uncertainty of identification should be expressed. Here is
percentage, to be used like in medical diagnostics (100% = fully
certain diagnosis), and qualifier ("near", "near but not", "not", ...).
There is an attempt to map the two with each other in the table
below. Certification of person who identifies the object is not
included here.
