[tdwg-content] DarwinCore 1.4 & 'lots'

Dear Kehan and others,

Lots are supported in all versions of Darwin Core in a simple way,
through the IndividualCount. The information about this term in the
proposed Darwin Core can be found in the Quick Reference Guide at
http://rs.tdwg.org/dwc/terms/index.htm#IndividualCount. Detailed
information about this concept, including all of the preceding
versions and the mapping to/from ABCD can be found in the Complete
History Guide at

In the case(/bottle/box/jar/tube/freezer ;-) ) where a lot is composed
of individuals of more than one ScientificName
(http://rs.tdwg.org/dwc/terms/index.htm#ScientificName) all under the
same catalog number, the recommendation is to apply the ScientificName
that accurately captures all of the samples in the cataloged
container. For example, if you had a cataloged box of sweat bees you
would put the number of individuals in the box in IndividualCount and
"Halictidae" in the ScientificName.  Any other attributes not shared
by all individuals in the lot could be captured at the level of
specificity shared by all individuals. Alternatively, such information
could be captured by enumerating the range of values represented in
the lot. For example, if the hypothetical box of sweat bees had both
adult individuals on pins and larvae in vials, Preparations
(http://rs.tdwg.org/dwc/terms/index.htm#Preparations) could be
populated with "whole animal (pinned), whole animal (ETOH)".

I hope that helps.
