Yes, skos:prefLabel and skos:altLabel I believe are also subproperties of rdfs:Label.

So you could do any of these but if you want it to have the name scientificName and be interpreted as
a rdfs:Label one way is to have it be either a subproperty of rdfs:Label or the skos:Label. In the end,
they are all interpreted as a kind of rdfs:Label.

I don't really see why this is so different from DC.

Yes, people using DC also have the problem in that they can't figure out do I put a URI here or a string?

If you look at the expected states in this example you will see the names for the states, that is because Sindice
knows to put in the label associated with the geoname URI. Otherwise you would see a geoname URI. The
same is true for the GNI names. The geonames label is from the GeoNames RDF, I simply mark these up
using the Geonames URI's. In a sense you use the URI and you get the label for "free"

< http://sig.ma/search?pid=e95218de8a57e4cda099116caa25c5ac >

The use of hasScientificName vs scientificName is simply to make the triples read more naturally.
It is not required.

<concept> dwc:hasScientificName "Puma concolor"

I think part of the problem we are having is that people are not recognizing how different RDF is from straight XML.

You really just have to add some variant of rdfs:Label in one of the files and all the other things that reference that
URI will get the label for free.

So as long as the GNI or Geonames RDF contains the label in it's RDF, I don't need include that in my RDF.

At the level of the cloud or the contents of the triple store the label only has to be associated with a particular URI
once.

For labels, would it perhaps make sense to use skos:prefLabel and skos:altLabel?
