For my participation in this annotation event, I added a new import format to my tool: a JSON file that we can download from Jon Udell’s site, filling in the url (http://dougengelbart.org/content/view/138/000/) and max, and then pressing the “JSON” button.

After importing this file into Condensr, the annotations will be shown as separate “cards” which can be rearranged, labeled with a “handle”, and connected across arbitrary threads. See an example here in the limited demo version http://x28hd.de/demo/?engelbart.xml

(However, if you download the full version which is equally free, you may export the map from the demo, and work with it more freely on your desktop,)
