       | I was asked to resubmit this new edition that I announced in HN
       | as it got finished on 2019-04-25:

       | 
       | The process took around a month in my spare time, and involved
       | copy-and-pasting the OCR plain text, then marked up as DocBook
       | XML, then converted with my own XSLT stylesheets into HTML5.
       | There were many transcription mistakes, some from OCR from the 35
       | year old daisy-printer monospace printout, some were in that
       | printout because of electrical noise in the printer serial line
       | in 1986. I fixed those I found by hand, then a couple of readers
       | have reported others.
       | 
       | Since then I've corrected more OCR errors, and polished a bit
       | more the HTML rendition.
       | 
       | From the introduction to this edition: "It features an instance
       | of Douglas Engelbart's implicit links, automatically linking all
       | appearances of certain terms to their definitions elsewhere in
       | this document. This is done through a Javascript function that
       | operates on the HTML content from the web server. It also shows
       | his structural statement numbers, those little labels to the
       | right of each paragraph that allow high resolution linking."
       | 
       | Doug Engelbart was not part of Xanadu, although he was a close
       | friend of Ted Nelson for decades. It's just that those aspects of
       | his NLS (of 1968 "Mother of all demos" fame) fit well this
       | document, and work relatively well on web browsers.
       | 
       | I did try to implement transclusion as an example, but the target
       | web server did not provide a CORS header and browsers refuse to
       | load their content.
       | 
       | This document goes into detail about the addressing scheme for
       | documents (https://sentido-
       | labs.com/en/library/201904240732/Xanadu%20Hy...), the enfilade
       | data structure (https://sentido-
       | labs.com/en/library/201904240732/Xanadu%20Hy...), their then-
       | future plans, etc.

         | Yo this is really cool! I'm glad you came back to update us.
