Internet Application Protocol Collation Registry
RFC 4790, “Internet Application Protocol Collation Registry”, is a Proposed Standard document published in March 2007 by C. Newman, M. Duerst, A. Gulbrandsen. The canonical text is published by the RFC Editor.
Abstract
Many Internet application protocols include string-based lookup, searching, or sorting operations. However, the problem space for searching and sorting international strings is large, not fully explored, and is outside the area of expertise for the Internet Engineering Task Force (IETF). Rather than attempt to solve such a large problem, this specification creates an abstraction framework so that application protocols can precisely identify a comparison function, and the repertoire of comparison functions can be extended in the future. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
