I’m more familiar with the Open Annotation model and RDF than I am with this Web Annotation model and JSON-LD direction (news to me today, in fact). But they seem conceptually interchangeable.
The XPath-y selectors could be added to your model using oa:FragmentSelector and some #xpointer(/my/path/to/something) value. http://www.openannotation.org/spec/core/specific.html#FragmentSelector I agree that the model is lacking when the quote of an annotation spans different elements and may require an additional property to specify which of (potentially multiple) oa:FragmentSelectors should be used for the start and end of the selection. Have you tried shoehorning the into/out of oa:FragmentSelectors? -ben > On Jul 30, 2015, at 9:25 AM, Benjamin Young <bigblue...@hypothes.is> wrote: > > On Thu, Jul 30, 2015 at 11:23 AM, Ben Leinfelder <leinfel...@nceas.ucsb.edu> > wrote: > Hi Benjamin, > I haven’t been following 2.x development closely, but I thought supporting an > Open Annotation model natively was on the TODO list for AnnotatorJS. > Sure enough, the road map lists it - > http://docs.annotatorjs.org/en/latest/roadmap.html > - Internal data model consistent with Open Annotation > - A (beta-quality) storage component that speaks OA JSON-LD > > Pretty sure that got pushed back to target a later release though that > decision is not yet reflected in the roadmap.
