A URL is a URI that, "in addition to identifying a resource, provides a means of locating the resource by describing its primary access mechanism (e.g., its network location)".
In theory "Cool URLs don't change". But that's never quite true.

Hyperlink provides a pure-Python implementation of immutable URLs. Based on RFC 3986 and RFC 3987, the Hyperlink URL balances simplicity and correctness for both URIs and IRIs.
