Hi Robert, don't get me wrong: For most of the RDF cases Open Annotation is fine. I was talking here about non-RDF use cases, e.g. HTML. You gave one example yourself: <a href="http://www.openannotation.org/spec/core/core.html#FragmentURIs">AnchorText</a> or <a href="http://en.wiktionary.org/wiki/house#English-abode">the meaning of house in the sense of abode</a> You can not put RDF into the "href" attribute and you would need extra infrastructure (a server + service for minting and resolving URIs) to send around a simple link. --Sebastian Am 03.05.2013 09:23, schrieb Robert Sanderson: > > Dear all, > > Thank you for the comments on Open Annotation! > > We agree, of course, that fragments are extremely important.
