Minutes of Darwin Core (DwC) Nomenclature - TDWG 2014
issue 1, Nomen
if nothing is decided NomenclaturalChecklist would be removed.
Further discussions needed as not all consequences have been fully discussed.
Decision: remove term!
issue 2 typifiedName
move to Identification group (Rich)
typeStatus definition needs updated
we should also have a new term to declare the typeSpecies/typeGenus (Walter)

Reprojecting coordinates according to their geodetic datum
For a long time Darwin Core has a term to declare the exact geodetic datum used for the given coordinate.
Quite a few data publishers have used dwc:geodeticDatum http://rs.tdwg.org/dwc/terms/index.htm#geodeticDatum for some time to publish the datum of their location coordinates.
Until now GBIF has treated all coordinates as if they were in WGS84 http://en.wikipedia.org/wiki/World_Geodetic_System, the widespread global standard datum used by the Global Positioning System (GPS). Accordingly locations given in a different datum, for example NAD27 or AGD66, were displaced on GBIF maps a little. This so called "datum shift" is not dramatic, but can be up to a few hundred metres depending on the location and datum. The Univeristy of Colorado has a nice visualization of the impact: http://www.colorado.edu/geography/gcraft/notes/datum/datum_f.html
At GBIF we thought it is about time now to interpret the geodeticDatum and reproject all coordinates as goo
