What is a URL? And What is a URI

All,

As the conversation about HTTP responses evolves, I am inclined to 
believe that most still believe that:

1. URL is equivalent to a URI
2. URI is a fancier term for URI
3. URI is equivalent to URL.

I think my opinion on this matter is clear, but I am very interested in 
the views of anyone that don't agree with the following:

1. URI is an abstraction for Identifiers that work at InterWeb scale
2. A URI can serve as a Name
3. A URI can serve as an Address
4. A Name != Address
5. We locate Data at Addresses
6. Names can be used to provide indirection to Addresses i.e., Names can 
Resolve to Data.

Hopefully, if we sort this out, we have one less point of confusion to 
address i.e. that overloaded term: Resource.
