I think this is what you are looking for:

<http://example.org/myannotation> a oa:Annotation ;

    oa:hasTarget <urn:uuid:074360F6-19F9-49A0-83BF-A07FEEF09D5E> ;

    oax:hasSemanticTag <http://dbpedia.org/page/Eiffel_Tower> .

  <urn:uuid:074360F6-19F9-49A0-83BF-A07FEEF09D5E> a oa:SpecificResource ;

    oa:hasSource <http://example.org/2012/07/18/news> ;

    oa:hasSelector <urn:uuid:9035e480-d152-11e1-9b23-0800200c9a66> .

  <urn:uuid:9035e480-d152-11e1-9b23-0800200c9a66> a oax:TextOffsetSelector ;

    oax:offset 97 ;

    oax:range 6 .

I'm struggling to understand how to annotate a specific text section identified by offset.

I see the example at http://www.openannotation.org/spec/extension/#SelectorOffset

oa:hasTarget points to the thing being annotated. Apart that I thing that a name like oa:annoates would be more easy to understand I think I'm getting this. The subject is the annotation and I can add hasSemanticTag properties to it.

The Object of oa:hasTarget isn't in this case the whole document but only a part of it. This selection is apparently represented by a oa:SpecificResource (here too I think the name is not very intuitive, isn't this rather a eg:DocumentSection). Now the selector part is quite understandable. For hasSoure I would guess this points to the document the subject is a section of but I read in the core spec that it is a letationship between the oa:SpeficResource and a (why does it says "the"?) resource that is a more specific reresentation of the subject. In this case so I'm looking for a more specific representation of the document section. What is a more specific representation? To me character 97 through 102 of a specific document is already quite specific. Confused.

Maybe somebody could jsut tell me, how to express

the character range from 97 to 102 of the resource <http://example.org/2012/07/18/news> are related to <http://dbpedia.org/page/Eiffel_Tower>
