It just wasn't "the scene" at the time. RDF/SPARQL had its world -- permeated throughout academia and some enterprise deployments with quad/triple-stores like AllegroGraph. But it wasn't going to make a PoW in the software industry because they didn't ride the razor-edge well enough.
OWL was a foolish mistake. Triple is a clean and simple idea, but in practice -- reification and URI character hell becoming mind numbing. The RDF-guys did nail it with SPARQL. That is such a pretty query language. Simple, intuitive. I haven't studied the recent path expression advances. I should.

But yea, lots of ways of fugglin' with the data.
