URL and URI

The terms URL (uniform resource locator) and URI (uniform resource identifier) are often used interchangeably, and very often, this is not correct.

More to read here: http://en.wikipedia.org/wiki/Uniform_Resource_Identifier

To me, a URL points to a physical path to get to the resource, such as one that points to a file or a web page.

On the other hand, a URI is a logical identifier, such as a namespace in a schema definition.
