I then decided I should just extend ReSpec.js (the framework we are using to publish) to just do this for us magically.  So far, so good.  I went in, made changes, got it all working, and hit a wall.

Yes:-) (if you consider me a real RDF semweb person, that is...)

The question is how bibo:abstract is defined, ie, whether it expects a literal or an object. I would expect the former. So I tried to find it, looking at:


and the range refers to Literal. So yes, my guess was right, and your latest version is indeed the right one...

So you do have the right instincts, even if you seem to fight with them:-)


> I struggle with similar things when trying to annotate Chapters (bibo has BookChapter, for example), references (dcterms has 'reference' but do we annotate the link to the reference, or do we annotate the actual reference in the References section?  And what is a subject and what is an object?  Help?
