To log and summarize a conversation we had.

Let's say I create a fixed resource, I pop the integer 3, in a text 
file, and save it on my server.

Now, I'll mint 4 different URIs which all point to the same 
network/fixed resource

1: http://xx.xx.xx.xx/foo
2: http://bar1.example/foo
3: http://bar2.example/foo
4: http://asldk.example/foo

Now, URI 1 uses the IP address and points to the number 3, that's it's 
meaning, it's just the number 3 (you know this because I just told you, 
use it however you want when you need to offer a representation of the 
number 3)

URI 2, I've minted because it is my birth month.

URI 3, I've minted because it's my partner, Rachel's, birth month.

URI 4, Bob minted because it's the number of children he has.

these are four different resources, even though network wise they are 
identical, and that's because the use of those URIs, the meaning or 
purpose of them, differs. They will be used in different scenarios for 
different purposes, they just are different.

this discussion came about because I asked if the URI, or the 
provenance, was a property of a simple-IR, if a simple-IR were a 
mathematical function where all its values were fixed, would the URI/ 
provenance be included in those properties - to distinguish it from the 
notion of a representation.
