Xanadu

- Ted Nelson's Xanadu Project idea began in 1960.
- Idea was publishers pay for storage and the user pays for delivery including a royalty (micropayment)
- This system would address the copyright issue through his transccopyright idea
- The word hypertext was originally coined by the creators of Xanadu
- Link is between one region of text and another region of text; unbreakable and unchangable
- Xanadu would also allow the direct inclusion of parts of other documents
- By 1995 Xanadu was considered vaporware
- Inspired Apple's Hypercard, LotusNotes & Mosaic
- 1998 Nelson shifted his emphasis to open source, and began the Zig-Zag software project
- In 1999 Nelson placed the Xanadu code unfinished into public hands, now Udanax
- Xanadu webstie now talks about the new Xanadu structure for the web. VLIT info can be found at mozdev.org and Sourceforge
