My idea of a semantic web is when the data on the web has value added to it by being able to tie disparate pieces of data together. The thrust of what Facebook is doing seems to be tieing my identity to data on the web. That's a different value prop.

One makes the web more usable to me, the other makes me more usable to other people.

But with the Open Graph protocol you do get the ability to tie disparate pieces of data together. For instance, let's say that I examine someone's tweet stream for links. If I fetch the OG data for each of those I can tell you whether they tweet most often about people, or movies, or whatever. I can show you a thumbnail display of images representing the things they linked to.

Open Graph is most definitely semantic web. Liking is just one possible application of that semantic data.

Oh yeah - I definitely agree.

I guess my thought was just that the semantic lens is focused in a different direction that I imagined. The mental model I always had was that the semantic info would let users make connections between datasets that model our physical world rather than datasets that monitor users themselves and how they use the web.

This is just a different use case than I imagined.
