Tim Berners Lee used concept maps in 1989
I was looking for something quite different just now, but ran across http://www.cybergeography.org/atlas/conceptual.html which led me to this:
“A concept map from Tim Berners-Lee’s original World-Wide Web proposal, a hypertext system called the “Mesh”, presented in 1989. See the full “Information Management: A Proposal”. (http://www.nic.funet.fi/index/FUNET/history/internet/w3c/proposal.html)
