If you ever need to briefly explain the semweb to your colleagues / employees / VCs, etc, then this diagram might be useful. I just found it in an old powerpoint presentation I used to deliver an introduction course to the Semantic Web, and it also made its way to a couple of VC presentations.



This is evidently for a tech savvy audience. In fact, it draws upon their understanding of the relation between different technological elements and their abstraction levels.

The interesting thing here is that it uses a simple and symmetric geometry to convey rythm and evolution. Therefore it makes it easy 1) for you to come up with a concise, ordered narrative and 2) for your audience to follow you and visually connect the semantic web to what they already know.

computers, files, resources
internet, www, ggg
physical location, filesystem, database
...

It is not perfect but it goes a long way very quickly and avoids overload. That's the whole point. You can then go into details if you wish.

Hopefully you will find it useful.
Feel free to use it, modify it, etc.
