soap and wikis

I had a dream last night. Someone was trying to explain how a soap semantic web binding was going to replace the web as we knew it. Somehow rather than writing content we are all just going to end up describing the relations of content to itself and to other content. After a long discussion in the dream, I still couldn't figure out why soap was the obvious choice for this sort of thing. Also, how do you actually get the relationships described. What does this have to do with wikis anyway? That was really important to the person making the presentation, but as far as I could tell actually unrelated to their topic.

This would be a perfectly natural dream to have if I did anything with the web these days. I don't. Why is my mind throwing this at me.
