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: [isbn:0393315703]
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[1] and the final version of the specification was released 16 December 2010. CURIE was never able to reach Recommendation status since the W3C XHTML2 Working Group's charter expired while the specification was in the Candidate Recommendation stage, but the final version of the specification notes that the CURIE specification was "considered mature and stable by the working group" at the time of publication.[2]
Example
This example is based on one from the aforementioned draft,[1] using a QName syntax within XHTML.
