 The forms, functions, and mandates of archival programs and institutions tend to differ based on geographical location and language, the nature of the society in which they exist and the objectives of those in control of the archives.Instead, the current standards that have been provided and are most widely followed, such as the ICA standard, ISO standard, and DIRKS standard, act as working guidelines for archives to follow and adapt in ways that would best suit their respective needs.Following the introduction of computer technology in archival repositories, beginning in the 1970s, archivists increasingly recognized the need to develop common standards for descriptive practice, in order to facilitate the dissemination of archival descriptive information.
