Here's a sample in N3 format:

@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix owl:  <http://www.w3.org/2002/07/owl#> .

@prefix opinneg: <http://opinml.org/2013/01/opinML/opinions/negative#> .

<mailto:[email protected]> opin:opinion :osn-12345 .
:osn-12345 opin:target <http://asdf.com/whatisasdf.html> ;
	opin:excerpt "asdf is a four letter word." ;
	opin:flag opinneg:Disagree ;
	opin:votevalue -1 ;
	opin:datestamp "2013-09-03 12:50:23.077589" ;
	opin:comment "asdf is not a word" .

The first two blocks above are header. The actual opinion starts with the mailto in the third block. OpinML files can contain multiple opinions.
