It's 2005 again!
These tools were pretty cool and an enormous amount of work was put into them.
The ontologies were extremely extensible. There just wasn't enough of an ecosystem putting them into practice and demonstrating their utility.
Their examples are nice:

That's Turtle, it's an awesome RDF serialization. https://www.w3.org/TR/turtle/
Imagine trying to convey this example in RDF/XML (that's more like 2005).
RDFa and microdata stuff for sharing got pretty far, but those are often simpler vocabularies (at least when seen from the outside, maybe folks who index that shit has something nicer going on, idk).
Honestly, I feel kind of relieved seen Netflix using this stuff. I suggested using this kind of tech to model knowledge in systems that had this problem of knowledge representation several times, but always had a hard time when people said "if it's so good, why no big player uses it?".
