Augusto,

I forgot to add this Google snippets link re. item #1: 
http://uriburner.com/c/IBJW3O .

How did you arrive at this problem via either of these URIBurner pages:

1. 
http://linkeddata.uriburner.com/about/html/http://vocab.e.gov.br/2011/03/vcge%01imigrantes 

2. 
http://linkeddata.uriburner.com/describe/?uri=http%3A%2F%2Fvocab.e.gov.br%2F2011%2F03%2Fvcge%23imigrantes 
.
