It usually works this way: you hear talking about 'semantic web' by someone who looks like he's knowing what's what, and you think " Wow, terrific, I'd like to know more". First, as normal, you ask enlightenment to those who look like knowing what's what, but most of the times the outcome is not encouraging. Strange talks, pseudo-technical big words, assorted esotericisms: in one word, the mystery deepens. Then you start smelling around on the web, but you can't get out of it , for it's difficult to spot something clear and meaningful in a massive amount of platforms, blogs, social pages and whatever. He who knows knows, and he who doesn't know will never do. Discouraged? Never and ever, because right now Flowerpower comes in. As we've already been through all of this and anything human isn't alien to us, we suggest a short online introductory course that we found very useful. It's a great starting point to cut through the fog and start putting stakes in the ground. Some other resources will come later, but now let's go with Cambridge Semantics.
