EML questions

[Christopher Jones]

Xiaoping,

You might take a look at this recent email thread on eml-dev as a starting point:

http://www.ecoinformatics.org/pipermail/eml-dev/2004-October/001027.html

Other folks have been grappling with the issue of start and end dates of 
datasets and projects as well.

Best,
Chris
