What is the Analogue for the Semantic Web? If the Web is like a Page+Links, the SW is like a...

In order to design an interface to support a technology, to expose its potential for what it can do, it helps to know what it is - or failing that - to have a model around which we can conceptualize what it is, what it does, and somewhat how it works. It's not unusual for a new technology or concept to be introduced via an analogue of a previous, familiar technology "it's like this thing - but for this new bit." This "like this, but for this new bit" is what i've been looking for, for the SW.

What i'll propose (eventually) below is that one paradigm may be a notebook in the traditional sense of the term of the notebook as a place to capture work in progress. taken one step (a big step) further, i'll argue that if the Web paradigm is a Page + Links, the paradigm for the Semantic Web may be a notebook + the memex.
