I see and agree with what you are saying. I retract the proposal to remove occurrenceDetails.<br><br><div class="gmail_quote">On Wed, Jul 6, 2011 at 10:42 AM, Paul J. Morris <span dir="ltr"><<a href="mailto:mole@morris.net">mole@morris.net</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I'd concur with John except for that pesky little word in the<br>
definition of dcterms:source, "derived"<br>
<div class="im"><br>
"A related resource from which the described resource is derived."<br>
<br>
</div>The history of recordURL, relatedInformation, and occurrenceDetails all have exactly the opposite meaning in my mind. All three of those were places to find additional information that was derived from some set of primary objects (specimen, field notes, map, etc). A publication that synthesises the most detailed information about an occurrence is derived from these primary sources of information. Carrying such a publication as a dcterms:source seems exactly backwards.<br>
<br>
I wouldn't mind using dcterms:source to indicate that a specimen label is derived from field notes or that a specimen label is derived from a ledger entry. However I would object to dcterms:source being used to indicate that a publication is the source of a specimen record, when the reality is almost certainly the other way around.<br>
<br>
I don't concur that the intent of dcterms:source is similar in definition or intent to occurrenceDetails.<br>
