Dear All,
I'm interested in referring to a GBIF distribution map in RDF, and am having fun figuring out how to do it. One way is to use a c-squares- based URI, see http://iphylo.blogspot.com/2010/05/referring-to-one-degree-s quare-in-rdf.html (http://tinyurl.com/33ba4kt).
The idea is that each 1° × 1° square in a GBIF map has it's own c- squares-based URI, e.g. http://bioguid.info/csquare:3317:364 , and hence a distribution would be a list of these URIs (perhaps with the number of records from each square).
Any thoughts on this approach, and whether we have an existing vocabulary to describe these relationships?
Regards
Rod
