I am using the 'identify' in the strict sense of 'denote'.
The semantic web is like a logic language in which URIs are symbols.

So, the URI, say denotes your home page.  You can use many things to  
*indirectly* identify yourself,
such as your email mailbox, home page, FOAF page, passport, and so on.

The word 'representation' is one which gets used with a very specific  
meaning too.
How about: you are its subject, it is about you. It indirectly  
identifies you as

"The person whose openid page is <http://mdavid.name>."
Written in N3,

[ openid:page <http://mdavid.name> ]

This use of terms in specific ways is always a trap of course. In  
common parlance we say 'Marmaduke, easily identified by his untidy  
shock of orange hair'

I hope this clarifies things.
