[tdwg-content] Any RDF example? Is this what the standard authors intended?

[Jaime Bosque]

Hi Pete and list,

first of all thanks for the quick response! I'm developing a semantic 
application based on a data retrieved from a database where several 
"observations" have been added by users (when I say "observation" i'm 
referring to an observation of an orchid in a specific time and specific 
location).

I've created an RDF containing 4 different resources (observations, 
users, organizations -group of users-, and taxons) that seems to be a 
mix of Simple DWC, DWC, and som FOAF terms you can check it here:

Any advice about how dealing with that data? I was considering in 
creating a new resource for the location terms but it's not worth as 
it's almost impossible have 2 observations in the same location...

Thanks list,
    Jaime

P.S -> URL's are not working as I'm using just a generic name instead of 
localhost.
