For sake of clarity I assume you meant:

What if I want to create a document that describes a person. And in that 
document I also want to state that I know the person I am describing.

## Turtle based RDF graph expression ##

a foaf:Document ;
foaf:maker <#i> .

foaf:knows <#PierreAnoineChampin> .

## End ##

Note: The RDF content (the graph) that ends being created at some 
location denoted by a URL will not contain relative URIs for <#i> or 
relative URI-URLs for <> . This is why I deliberately distinguish the 

1. RDF Model
2. RDF Syntax -- S->P->O  statements (3-tuples)
3. RDF Syntax Notation -- e.g., Turtle (one of many)
4. RDF Serialization Format -- the actual RDF graph that ends up being 
created by generated by an RDF processor that supports one or more RDF 
syntax notations.

#4 doesn't contain relative URIs or URLs.

I've noticed that #3 is sometimes referred to as surface syntax.
