@paulopinto I suspect the final book will have some additional material, but an early draft can be found at mitpressonpubpub.mitpress.mit.edu/annotatio...
@paulopinto There are two types of annotations you may see on the PubPub platform. Some are done with Hypothes.is (which you'll only see if you're using their browser plugin or other means) and the annotations which are custom built into the PubPub system (these require you to create an account).
@paulopinto I'm tinkering at a stand-alone micropub client to do the work, but it'll be a while before I'm finished. In the meanwhile, I'm using an IFTTT recipe to port the Hypothes.is RSS Feed for my account to my micropub endpoint using this method.
