A standard for the Ruby language and library is being drafted by the Information-Technology Promotion Agency, Japan (www.ipa.jp). Both English and Japanese-language versions are planned. It is expected that this specification will be adopted as a Japanese national standard by the end of 2010, and that, soon after, it will be Fast Tracked to ISO/IEC JTC 1, where it will be assigned to SC 22. The Fast-Track process takes a minimum of a year from submission to publication as an ISO/IEC standard.
