From the National Information Standards Organization, “a draft Question/Answer Transaction Protocol (pdf, 52 pages) that supports Q&A between library patrons and reference sources has been released for a one-year trial use period April 5, 2004-April 5, 2005…The Protocol defines a method and structure for data exchange between digital reference service domains. This new standard supports digital reference services, a new and rapidly growing extension of the traditional reference assistance, a mainstay of library operations.”
