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. | 0des wrote: | > "It features an instance of Douglas Engelbart's implicit | links, automatically linking all appearances of certain terms | to their definitions elsewhere in this document.
