päivitysputki

Päivitysputki refers to a type of criterion in classification systems, particularly in libraries and archives. The term is derived from Finnish, where "päivitys" translates to updating or renewal, and "putki" means pipe or conduit. The term is used to describe a mechanism for updating or replacing outdated information or classification systems.

In the context of classification and cataloging, päivitysputki can refer to a bridge or transitional section between two classification systems or scheme versions. This can happen when a library or institution transitions to a new classification system or when it updates to a newer version of an existing system. The päivitysputki serves as a buffer zone, allowing for the classification of materials that contain outdated or intermediate information.

The concept is essential in library science, particularly in times of system updates or large-scale cataloging efforts. It enables libraries to ensure that the classification of materials remains consistent and follows the hierarchical structure of the new or updated system. The päivitysputki also allows for the gradual replacement of outdated information, minimizing disruptions to library patrons and reducing the complexity of the update process.

Päivitysputki is a specialized concept that can be understood with knowledge of library classification and cataloging procedures. Its implementation requires understanding the specifics of the classification systems involved as well as the update process or transition occurring within the library or institution.
