[tdwg-content] dwc: city to county

Thanks for the clarification. So indeed I am trying something
locationID is not meant for. I am thus not proposing to change

However, I believe what I am describing is a very valid use case.

It seems to me to be a gap in Darwin Core in principal to be unable to
transmit Gazetteer IDs for the kind of object that are present in
Gazetteers (which to all my experience, never provider IDs for the
ditch 10 m away from the street intersection (which may have an ID).

I believe in most cases it is *interesting* (for re-finding purposes)
to have a free-form very detailed location description, but
*sufficient* for all analysis purposes to have a higher-level location
amendable to analysis.

It seems to me undesirable to be able to analyse records where the
collectors did not care to add detailed information (such as in a
collection only citing the city name) and unable to analyse any
records where in addition to the same city name a careful collector
also provided additional information. However, according to your
definitions, this is presently the situation with DWC.

Is there any way to make Darwin Core able to transmit such
information? Iif LocationID is not the correct property - which
property is the correct one?


Separately, and referring back to the start of the question: do you
plan to change DWC so that it is possible to transmit the name of
cities or villages.

Or could we even accept the IPTC Extension 1.1 as a relevant standard
and accept its definitions (I previously wrongly quoted a version 2, I
meant the 1.1. Also note that these fields are not new, they have been
moved from core to extension.

The link to the specs is here:


It defines for the {location detail} class the following properties
(available as RDF vocabularies)

World Region
Country ISO-Code
Country Name
Province or State
Location Details
