An urn can refer to two different things:
-
An urn is a vase, often with a cover, with a typically narrowed neck above a rounded body and a footed pedestal. It is often used for funerary purposes, either to hold the cremated ashes or as grave goods, but is used in many other contexts as well.
-
A Uniform Resource Name (URN) is a permanent identifier for internet resources that employs the urn scheme. It is essentially a location-independent string of characters that identifies every resource on the internet, regardless of its form, such as a website or email. URNs are defined namespaces assigned by a namespace authority, so they remain unique and persistent over time even after the resource they are attached to moves or ceases to exist.
