Hi Rupert
Thanks, this explains it.
In the archetype generated example there's following code:
UriRef textAnnotation =
> EnhancementEngineHelper.createTextEnhancement(ci, this);
> metadata.add(new TripleImpl(textAnnotation, RDFS.comment,
> new PlainLiteralImpl("A text of " + content.length() +
> " charaters")));
>
I guess TextEnhancement is the wrong type for such a comment on the text as
a whole. Which type shold be used instead?
Cheers,
Reto
