The CURIE Syntax 1.0 document is a W3C Working Draft, authored by Shane McCarron of Applied Testing and Technology, Inc., and Mark Birbeck. It provides a way to express URIs in a compact way that is independent of the language in which the compact URI (CURIE) is being used.
From the abstract:
The aim of this document is to outline a syntax for expressing URIs in a generic, abbreviated syntax. While it has been produced in conjunction with the HTML Working Group, it is not specifically targeted at use by XHTML Family Markup Languages. Note that the target audience for this document is Language designers, not the users of those Languages.
