Eml-Dev,
Matt and I discussed this task openly in the eml channel of the
ecoinformatics IRC. I asked one of the contacts at EPA some questions
regarding the intent, versioning and scope of this EDR form. After these
clarifications and discussions we concluded that we will submit the
enclosed excel doc.(or some modification of it) as a first version, with
only the "required" fields filled out. Other modifications may be made
at a later time (the EPA has a versioning control system in place). If
you want to add things here, please send to this list or to me. I will
send this 1st version early next week.
Last, we should register the XML schema in the EPA's XML registry
Thanks, Inigo
