[tdwg-content] Any RDF example?

Dear list,

As far as I've been working with DWC I've been just using Simple Darwin Core in XML files but now I'd like to add semantic information and therefore I've planned to use RDF.

I've been looking around but couldn't find any good example of a DWC RDF, could you please provide me with one? Even better if it contains the FOAF info of the author... :)

Thanks in advance, Jaime
