Joel, 
Thanks for the summary. Note that several services are already planned as
part of the improvements for the CoL in the 4d4life and i4life projects,
including annotation services. I'll try to include the ideas from Rod Page
in the discussions about the new CoL services to implement.

Wouter

> Here are some of my immediate observations:
> 
> 1. Darwin Core is almost exactly right for citizen science. However,
> there
> is a desperate need for examples and templates of its use. To
> illustrate
> this need: one of the developers spoke of the design choice between "a
> simple csv file and a Darwin Core record". But a simple csv file is a
> legitimate representation of Darwin Core! To be fair to the developer,
> such a sentence might not have struck me as absurd a year ago, before
> Remsen said "let's use DwC for the bioblitz".
> 
> We provided a couple of example DwC records (text and rdf) in the
> bioblitz
> data profile [1]. I  think the lessons learned document should include
> an
> on-line catalog of cut-and-pasteable examples covering a variety of use
> cases, together with a dead simple desciption of DwC, something like
> "Darwin Core is a collection of terms, together with definitions."
> 
> Here are areas where we augemented or diverged from DwC in the
> bioblitz:
> 
> i. We added obs:observedBy [2], since there is no equivalent property
> in
> DwC, and it's important in Citizen Science (though often not
> available).
> 
> ii. We used geo:lat and geo:long [3] instead of DwC terms for latitude
> and
> longitude. The geo namespace is a well used and supported standard, and
> records with geo coordinates are automatically mapped by several
> applications. Since everyone was using GPS  to retrieve their
> coordinates,
> we were able to assume WGS-84 as the datum.
> 
> If someone had used another Datum, say XYZ, we would have added columns
> to
> the Fusion table so that they could have expressed their coordiantes in
> DwC, as, e.g.:
> DwC:decimalLatitude=41.5
> DwC:decimalLongitude=-70.7
> DwC:geodeticDatum=XYZ
> 
> (I would argue that it should be kosher DwC to express the above as
> simply
> XYZ:lat and XYZ:long. DwC already incorporates terms from other
> namespaces, such as Dublin Core, so there is precedent for this.
> 
> 2. DwC:scientificName might be more user friendly than
> taxonomy:binomial
> and the other taxonomy machine tags EOL uses for flickr images.  If
> DwC:scientificName isn't self-explanatory enough, a user can look it
> up,
> and see that any scientific name is acceptable, at any taxonomic rank,
> or
> not having any rank. And once we have a scientific name, higher ranks

> 4. We didn't include "basisOfRecord" in the original data profile, and
