Seeing this PR driven newsblurb about the Inktomi search toolkit's availability and use of XML structures reminded me of the joys of search engines. Like, what ever happened to the START initiative that the now subsumed Infoseek was deep into. Was it disintermediated by the XML revolution that followed? Since I can no longer find good resources on it (yet), maybe it just drifted away in bit rot. How would it have worked if integrated with Neurogrid? Much learning and reading to do there still.
