Matt,
If we agree to stick with the present EML keywords
theme, place, stratum and temporal, I can change the Web form script
(load-dataset.cgi) to include a taxonomic keyword (to go into taxonomicCov,
keywtax, taxonkey) an a "none" (to be dropped in the XML file). Is there
anything else we need to consider for the Web form?
For the EML-DEVers who may not recently have looked at the Web forms, they
are at
http://knb.ecoinformatics.org/cgi-bin/load-dataset.cgi?cfg=nrs
and
