reference needed

I've been trying to find a reference to an issue that I read about a few 
weeks ago and now can't remember where I saw it. The situation goes like 
this:

Suppose we want to represent a real world object with a URL. We put a 
web page at that URL describing the object. Now, when we make statements 
in RDF (or DAML, or OWL) with that URL as the subject or object, there 
is a potential confustion about whether the statement is about the web 
page or about the object that the web page describes. For instance: if a 
web page describes a particular copy of "War and Peace" and we have an 
RDF statement that the author of 
"http://www.mybook.net/WarAndPeace.html" is "Leo Tolstoy", does that 
mean that he wrote the book, or the web page?

This is apparently a topic that has received thorough discussion, and 
even has a name, so I don't want to talk about it here. I'm just hoping 
someone can point me to a paper or something that covers this topic.Or 
just the name of the topic would be enough to start with.

Thanks,
