Pete,<br>
Thanks for the response about term resolution. I'm over my head on
that topic, so I'll let others respond to that part.<br>
<br>
With regards to a vocabulary that uses URIs rather than literals, I'm
in favor of that. At one point in a previous discussion, I think it
was suggested that separate terms be created for literal and URI
versions of terms like dwc:recordedBy. At first I liked that idea, but
after thinking about it and playing with it for a while, I think that
the suggestion of just applying a label property to the resource
identified by the URI is simpler and wouldn't require a proliferation
of new terms. For example:<br>
<br>
<dcterms:creator><br>
<rdf:Description
rdf:about=<a class="moz-txt-link-rfc2396E" href="http://biocol.org/urn:lsid:biocol.org:col:15539">"http://biocol.org/urn:lsid:biocol.org:col:15539"</a>><br>
<rdfs:label>University of Louisiana at Monroe
Herbarium</rdfs:label><br>
</rdf:Description><br>
</dcterms:creator><br>
<br>
could be used if both a literal and URI were available and <br>
<br>
<dcterms:creator>University of Louisiana at Monroe
Herbarium</dcterms:creator><br>
<br>
could be used if a URI were not available. It seems like it should be
relatively easy for a linked data client to have contingencies to deal
with this. Even with technology that's semantically "dumb" like XSLT,
it's pretty easy to code for the two possibilities.<br>
<br>
But I suppose it would be good to have some kind of consensus that this
is the preferred approach. Otherwise, separate terms might be better.
There aren't a whole lot of dwc terms to which this situation would
apply.<br>

<div>By "efficient", I mean a vocabulary that uses standard
resolvable URI's instead of literals for standard terms etc. This
solution would also avoid the problem that Markus just mentioned. </div>
<div><br>
</div>
<div>I am also wondering if the "individual" definition should be
changed to mean one individual organism rather than a potential
collection of individuals. Individuals from the same colony could be
represented using a separate related vocabulary. Allowing multiple</div>
<div>individuals will cause problems for consuming applications. For
instance, is the queen a separate individual or not? How do you
differentiate between a photo of the queen vs. a photo of one of the
workers. There are also potential problems even if the individuals</div>
<div>are all workers.</div>
<div><br>
</div>
<div>I have been thinking that for some attributes like character
states, it might be best to have a family level ontology. In this
example, you might have a "formicidae_ontology", that could be used to
deal with individuals from the same colony as well as ant specific
character states.</div>

I first I looked up<br>
<a moz-do-not-send="true" href="http://purl.org/dc/terms/creator"
target="_blank">http://purl.org/dc/terms/creator</a><br>
and all four clients reported the properties of the term. Then I tried<br>
<a moz-do-not-send="true"
href="http://rs.tdwg.org/dwc/terms/basisOfRecord" target="_blank">http://rs.tdwg.org/dwc/terms/basisOfRecord</a><br>

<a moz-do-not-send="true"
href="http://validator.linkeddata.org/vapour" target="_blank">http://validator.linkeddata.org/vapour</a><br>
validation on the basisOfRecord URI and got the following message:<br>
<br>
Vapour was unable to complete the request due to the following
exception:<br>
<br>
ForbiddenAddress: forbidden request from 98.87.45.8 to <a

(resolves to IP 192.38.28.106), internal IP addresses are forbidden<br>
<br>
I have no idea what that means, but all of this seems to mean that<br>
Darwin Core is currently "broken" from a Linked Data point of view.<br>
