Annotations: interacting with the Annotea RDF store

If time, go thru the protocol document, otherwise, use the following content

• Standard HTTP methods for publishing (PUT), updating (PUT, POST), deleteting (DELETE)
• Problem: how to publish an RDF statement without knowing its URI?

  --> solution: have the server assign it an URI and discard the previous one

• Retrieval done thru a customized HTTP GET Query

  GET /Annotation?w3c_annotates=http://serv1.example.com/some/page.html HTTP/1.1
  GET /Annotation?w3c_reply_tree=http://annotea.example.org/Annotation/3ACF6D754 HTTP/1.1

  --> works, but this is not a generic RDF store query (see Algae)

• Retrieval of annotations metadata is separate from the retrieval of the annotations body

  --> download the body only if you need to see it
