CURIE

In computing, a CURIE (or Compact URI) defines a generic, abbreviated syntax for expressing Uniform Resource Identifiers (URIs). It is an abbreviated URI expressed in a compact syntax, and may be found in both XML and non-XML grammars. A CURIE may be considered a datatype.

An example of CURIE syntax:

The square brackets may be used to prevent ambiguities between CURIEs and regular URIs, yielding so-called safe CURIEs.

QNames (the namespace prefixes used in XML) often are used as a CURIE, and may be considered a type of CURIE. Unlike QNames, the part of a CURIE after the colon does not need to conform to the rules for XML element names.

The first W3C Working Draft of CURIE syntax was released 7 March 2007.

The final recommendation was released 16 December 2010.

Example
This example is based on one from the aforementioned draft, using a QName syntax within XHTML.
