“More than 30 years after he began developing the software
project that would become a precursor to the World Wide Web,
hypertext creator Ted Nelson is making available portions of his
Xanadu software code to the open source development community.”
“Nelson, professing to want ‘intellectual credit’ for his
two-way document-linking system, said he is releasing the software
code so that developers can work on the browser version of the
Xanadu project. Nelson has packaged the two principal entities of
the Xanadu code, versions 88.1 and 92.1, under the names ‘Udanax
Green’ and ‘Udanax Gold.'”
