Can you see the nuts and bolts?

I don't think there's any real argument about whether or not we map 
things we can see. There may be disagreements about *how* we map them, 
but the basic principle that we map what is visible is, I think, pretty 
firmly established.

The basic question here is how we go about mapping things which you 
can't see - intangibles, such as administrative boundaries, postcodes, 
road numbers, etc. And that's where questions of relevance come into it.

It's free, but it isn't unrestrained. You can't just make up entries. 
You can't put Ambridge and Hogwarts on the map (although you can, now, 
include Platform 9 3/4). You can't label a road as a river and a wood as 
a skyscraper. To be useful, we have to agree to a common set of 
principles and then stick to them.
