Re: How to model the content from a document?

NIF produces blank node free RDF, which is simple to understand and  
flexible to use:  
http://svn.aksw.org/papers/2012/WWW_NIF/public/string_ontology.pdf

The basic idea is to model Strings in Context.

So you have a document:
http://www.w3.org/DesignIssues/LinkedData.html

And you want to refer to its content (all characters from 0 to the end ):
http://www.w3.org/DesignIssues/LinkedData.html#offset_0_26546

Now you define the content as the Context and say, that it occurs in  
the Document:
@prefix : <http://www.w3.org/DesignIssues/LinkedData.html#>
:offset_0_26546 a str:Context ;
   str:occursIn <http://www.w3.org/DesignIssues/LinkedData.html> .

Additionally you can say that a substring occursIn a paragraph:
:offset_600_1000 a str:String ;
   str:referenceContext :offset_ 0_26546 .
   str:occursIn <yourparagraphuri> .

Or you can model each paragraph as a different context:

:offset_600_1000 a str:Context ;
    str:occursIn <yourparagraphuri1> .
:offset_1001_2000 a str:Context ;
    str:occursIn <yourparagraphuri2> .

The only drawback is that there is only an old owl ontology for NIF  
1.0 http://nlp2rdf.org/nif-1-0 . NIF 2.0 will not be backwards  
compatible:
nlp2rdf.org/news/nif-roadmap-2012-and-pointers

We hope to have it ready in two months.
All the best,
Sebastian
