[tdwg-content] To what Occurrence records should recordedBy be applied?

[Steve Baskauf]

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. 

This message is related to a DwC clarification given by John Wieczorek 
in http://lists.tdwg.org/pipermail/tdwg-content/2010-January/000219.html

in response to my post

http://lists.tdwg.org/pipermail/tdwg-content/2009-December/000201.html

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".

That is a more specific way of defining the applicability of recordedBy 
than the word "original" in the term definition.

 

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.  I suppose that could be a matter of preference - 
it's probably more important that the dwc:collector be properly recorded. 

 

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.  The 
problem is that if the chain of derivation becomes too complicated, it 
becomes unclear what the "original" Occurrence is.  What about the 
situation in example 3:

http://people.vanderbilt.edu/~steve.baskauf/conceptual-scheme-botanical.gif

which is a relatively realistic circumstance in a botanical garden?  
Would I give a dwc:recordedBy value to the DNA 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 DNA 
sample from the living specimen?  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.  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).
