An example of CURIE syntax:

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

In computing, a namespace is a set of signs (''names'') that are used to identify and refer to objects of various kinds. A namespace ensures that all of a given set of objects have unique names so that they can be easily identified.

) often are used as a CURIE, and may be considered a type of CURIE. CURIEs, as defined by the
W3C, will be better defined and may include checking. 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.
