RFC3986 : 1.1.3:
| A URI can be further classified as a locator, a name, or
| both. The term "Uniform Resource Locator" (URL) refers
| to the subset of URIs that, in addition to identifying a
| resource, provide a means of locating the resource by
| describing its primary access mechanism (e.g., its
| network "location"). The term "Uniform Resource Name"
| (URN) has been used historically to refer to both URIs
| under the "urn" scheme [RFC2141], which are required to
| remain globally unique and persistent even when the
| resource ceases to exist or becomes unavailable, and to
| any other URI with the properties of a name.
|
| An individual scheme does not have to be classified as
| being just one of "name" or "locator". Instances of URIs
| from any given scheme may have the characteristics of
| names or locators or both, often depending on the
| persistence and care in the assignment of identifiers by
| the naming authority, rather than on any quality of the
| scheme. Future specifications and related
| documentation should use the general term "URI" rather
| than the more restrictive terms "URL" and "URN"
| [RFC3305].
