EXAMPLE USAGE:
Super-easy method to say you like the band Coldplay:
<#me> like:likes <http://dbpedia.org/resource/Coldplay> .
Or providing a rating (between 0.0 and 5.0):
<#me> like:opinion
[ a like:Opinion ;
like:regarding <http://dbpedia.org/resource/Coldplay> ;
rev:rating 4.5 ] .
Here, no rating is provided, but all PositiveOpinions have a rating
of more than 3.0 by definition:
<#me> like:opinion
[ a like:PositiveOpinion ;
like:regarding <http://dbpedia.org/resource/Coldplay> ] .
This, however, means you like the Wikipedia article about
Coldplay, but doesn't indicate whether or not you like the band:
<#me> like:likes <http://en.wikipedia.org/wiki/Coldplay> .
This vocab provides a "like:likes_topic_of" term for linking
to articles. It's a little ambiguous - the following could
mean that I like the Wikipedia article about Coldplay, or that
I like the band themselves - or perhaps both!
<#me> like:likes_topic_of <http://en.wikipedia.org/wiki/Coldplay> .
