Hey, thanks for your feedback. You're right; this is basically what the Semantic Web was trying to do. In earlier attempts to explain the idea I had mentioned Web 3.0 (that is to say, the 'original' Web 3.0), but wasn't sure enough people remembered it to be pertinent (I could certainly be wrong on this point).

I think the Semantic Web had a lot of promise, but it simply got too academic, with layers and layers of committees dedicated to ontologizing the entire world in a way that became progressively more detached from the needs of users and developers. As far as I could tell from my research, this was a stark reversal of the earliest ideas behind Web 3.0, which were more about establishing the 'meaning' of a piece of data in a decentralized way. Had the Semantic Web stayed the course on decentralization I think we may have seen a dramatically different outcome.

If you feel that this post didn't pay enough homage to the work that came before, that's a fair critique and I apologize. The concept of a Schema Network is definitely inspired by a lot of ideas that were in vogue in the Web 3.0 days.
