Following the Darwin Core Term Change Policy
(http://rs.tdwg.org/dwc/terms/namespace/index.htm#classesofchanges), I
am hereby submitting a request for the addition of a new Darwin Core
term: georeferencedDate.
I've also submitted this request as an issue on the Darwin Core Google
Code site: http://code.google.com/p/darwincore/issues/detail?id=104

Term Name: georeferencedDate
Identifier: http://rs.tdwg.org/dwc/terms/georeferencedDate
Namespace: http://rs.tdwg.org/dwc/terms/
Label: georeferencedDate
Definition: The date on which the georeference of the Location was
determined. Recommended best practice is to use an encoding scheme,
such as ISO 8601:2004(E).
Comment: Example: "2011-03-01T13:59-0500" is 1 Mar 2011 1:59pm in the
time zone five hours earlier than UTC.
Type of Term: http://www.w3.org/1999/02/22-rdf-syntax-ns#Property
Refines: http://purl.org/dc/terms/date

ABCD 2.06: not in ABCD

Submitter: Peter Desmet

Justification: A georeferencing date allows chronological sorting of
multiple georeferences for one location, identification of the most
recent georeference, etc. This term is already used at georeferencing
workshops (based on the GBIF 2006 Guide to best practices for
georeferencing) and in numerous collection databases. It will also
become one of the outputs of the new BioGeomancer.
It's justification is similar to the one for dateIdentified.
The term could be called "dateGeoreferenced" (cf. "dateIdentified"),
"georeferenceDate" (cf. "georeferenceProtocol" and "eventDate") or
"georeferencedDate" (cf. "georeferencedBy").

Thank you for reviewing this request.
