ISO/IEC 15897 (Procedures for the registration of cultural elements) is an ISO/IEC standard for the registration of new POSIX locales and POSIX charmaps. This standard is the result of a "fast-track" adoption of CEN ENV 12005, a European prestandard published by CEN. It was originally published in 1999, and a second edition was published in 2011. The standard was produced by Working Group 20 (WG20) of the JTC 1/SC 22 committee, but in 2006 the standard was transferred to the JTC 1/SC 35 committee. The registry is maintained by Danish UNIX-systems User Group (DKUUG), although it has not been updated since December 2001. The standard was confirmed in 2017, following a five-yearly systematic review. Items registered in the registry are: Narrative Cultural Specifications POSIX Locales POSIX Charmaps Repertoiremaps It overlaps somewhat with the CLDR project hosted at the Unicode Consortium.
