How many research grants have been awarded to “Semantic Web” research proposals over the last few years? I always maintained that this is a typical academic solution to a problem that will be solved by very simple additions to the existing web like microformats.
Now the search heavyweights have joined the semantic web for real. But not by doing RDF or any of those full blown perfect solutions developed over the last years by burning research money.
As I see it, most of the research projects are now completely obsolete given the launch of schema.org.
