Hyperbole aside, v2.x has been the best RDF database on the market (or OSS, for that matter). Its a bit rough around the edges (you'll be talking to their very helpful support frequently), but the performance with large datasets is significantly better than Sesame, Jena, etc.
The "Web 3.0" stuff is bullshit (anything mentioned "Web x.y" invariably is), but the actual Franz database is an interesting product with some cool technology inside it.
it would be a lot more interesting if it was an open source project... unfortunately, I'm not very keen on vendor lock-in with a small company especially when there's so many other choices
Web 3.0 is based on simplicity. Even simpler than web 2.0. Now there are just blank screens + white noise with backend tags for a semantic, metaphysical experience.
Actually, it was my understanding that web 3.0 will have photorealistic textures in rendered in super mega HD resolution, with weather supplied by 2 crays working together, along with economic simulations from the university of tokyo and a unique "circle of life" designed by peter molineux. as an homage to linden labs, they are going to call web 3.0 "Real Life".
unfortunately, all structure and order will be seen as elitist, discriminatory and requiring too much "lock-in" and as such, it will provide no use to anyone seeking to accomplish things.
