Editing Transclusion (section)

==History and implementation by Project Xanadu==
Ted Nelson, who originated the words ''hypertext'' and ''[[hypermedia]]'', also coined the term ''transclusion'' in his 1980 book ''[[Literary Machines]]''. Part of his proposal was the idea that [[micropayment]]s could be automatically exacted from the reader for all the text, no matter how many snippets of content are taken from various places.

However, according to Nelson, the concept of transclusion had already formed part of his 1965 description of [[hypertext]].<ref>Theodor H. Nelson, "A File Structure for the Complex, the Changing and the Indeterminate." Proceedings of the ACM 20th National Conference (1965), pp. 84-100</ref>  Nelson defines transclusion as, "...the same content knowably in more than one place," setting it apart from more special cases, such as the inclusion of content from a different location (which he calls ''transdelivery'') or an explicit [[quotation]] that remains connected to its origins, (which he calls ''transquotation'').

Some hypertext systems, including Ted Nelson's own [[Project Xanadu|Xanadu Project]], support transclusion.<ref>{{Cite web|url=http://info.iicm.edu/iicm_papers/transclusions_in_HTML-based_environment.pdf|title=Transclusions in an HTML-Based Environment|last1=Kolbitsch|first1=Josef|last2=Maurer|first2=Hermann|date=January 27, 2017|access-date=January 27, 2017|archive-date=July 1, 2017|archive-url=https://web.archive.org/web/20170701160301/http://info.iicm.edu/iicm_papers/transclusions_in_HTML-based_environment.pdf|url-status=dead}}</ref>

Nelson has delivered a demonstration of Web transclusion, the Little Transquoter (programmed to Nelson's specification by Andrew Pam in 2004–2005).<ref>[http://www.xanadu.com.au/transquoter/ The Little Transquoter] Xanadu.com.au</ref> It creates a new format built on portion addresses from Web pages; when dereferenced, each portion on the resulting page remains click-connected to its original context.
