One of our goals for our “platform for reading” deliverable is to enable annotation. For the last six or so months, we’ve been working with Evident Point and Hypothes.is to make that happen. Evident Point is a Vancouver-based software company with expertise in the open-source reading platform Readium, and Hypothes.is is an open-source project to create an annotation layer on the open web. Check out the Hypothes.is blog post announcing the results of our collaboration. The post also links to a demo of Hypothes.is in Readium, and a demo of Hypothes.is in EPUB.js (another open-source web reader).
