Some resources are quite simple and straightforward to understand, e.g. 
http://purl.uniprot.org/uniparc/UPI00001328C5 represents a specific amino 
acid sequence, and e,g, http://purl.uniprot.org/taxonomy/9606 represents a 
specific organism (though there are some complications there, too...)

The resources in the http://purl.uniprot.org/uniprot/ namespace are a bit 
more complicated, basically it's annotation for a sequence in an organism:

http://purl.uniprot.org/uniprot/P60484 (Human)
http://purl.uniprot.org/uniprot/P60483 (same sequence, but Dog)

...but these resources may also include annotation for related sequences 
produced e.g. by alternative splicing:

http://purl.uniprot.org/uniprot/P00750 (Human, 3 sequences)

...provided the function of the resulting sequences are not so different 
that they warrant resources of their own...
