Nice. Creating URIs from descriptions of resources is a recurrent  
problem, so it's great to see a proposal in this space!

I had a look at the documentation and didn't quite manage to grasp how  
it works in detail. The documentation is mostly just a usage example,  
which is a nice start but doesn't quite do it for me. Looking at the  
N3 for rdfs:comments also didn't help much.

I think that URI Templates [3] might be a handy companion syntax for  
CoIN and I wonder if they could be integrated into CoIN. I'm thinking  
more about the general curly-brace-syntax rather than the fancy  
details. So perhaps you could start with something like

http://example.org/publ/{publisher}/{document}
http://example.org/publ/{publisher}/{document}/rev/{date}
http://example.org/profiles/{name}

and then attach further information to those {foo} parts, e.g. a  
TokenSet and the represented property.

Anyway, nice work.

Best,
Richard
