This is a follow-up to the email that I just sent to the list. It is
an issue that I see as related to the issues I raised in the other
email. <br>
<br>
<p class="MsoNormal">This message is related to a DwC clarification
given by John Wieczorek in
<a class="moz-txt-link-freetext" href="http://lists.tdwg.org/pipermail/tdwg-content/2010-January/000219.html">http://lists.tdwg.org/pipermail/tdwg-content/2010-January/000219.html</a></p>
<p class="MsoNormal">in response to my post</p>
<p class="MsoNormal"><a class="moz-txt-link-freetext" href="http://lists.tdwg.org/pipermail/tdwg-content/2009-December/000201.html">http://lists.tdwg.org/pipermail/tdwg-content/2009-December/000201.html</a></p>
<p class="MsoNormal">With regards to John's email, it seems clear to me
that the subject of
dwc:recordedBy should be Occurrences derived directly from Individuals,
i.e.
those which in the examples of my previous
email which have gray arrows and would have been given
"documentsDistribution" values of
"True".</p>
<p class="MsoNormal">That is a more specific way of defining the
applicability of
recordedBy than the word "original" in the term definition.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I agree with what John said in his post that the
dcterms:creator may not be the same as dwc:collector in many
circumstances, but
I think in his example of a specimen preparator, I would provide the
name of
the institution as dcterms:creator rather than the person who was the
specimen
preparator.<span style=""> </span>I suppose that could be a
matter of preference - it's probably more important that the
dwc:collector be
properly recorded.<span style=""> </span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm not sure what I think about John's statement
that the
dwc:recordedBy value for Occurrence resources with
”documentsDistribution"
values of true should be applied to all of the resources derived from
them.<span style=""> </span>The problem is that if the chain
of derivation becomes too complicated, it becomes unclear what the
"original" Occurrence is.<span style=""> </span>What
about the situation in example 3:</p>

<p class="MsoNormal">which is a relatively realistic circumstance in a
botanical
garden?<span style=""> </span>Would I give a dwc:recordedBy
value to the <st1:stockticker w:st="on">DNA</st1:stockticker> sample,
and if I
did would it be the name of the person who collected the seed, the
person who
planted the seed in the garden, or the person who collected the <st1:stockticker
w:st="on">DNA</st1:stockticker> sample from the living specimen?<span
style=""> </span>It seems to me that it would be better to
recommend that a value for dwc:recordedBy be given for all Occurrences
that
would have a "documentsDistribution" value of true, but to make its
assignment optional for any resource where
"documentsDistribution"=false.<span style=""> </span>If users want to
know who collected the
"original" Occurrence resource, let them trace the origin of the
Occurrence resource back to the first resource that was derived from
the
Individual (how to do that is another can of worms that I will not open
here,
although I do have an answer to that question).<span style="">
