ARK (Archival Resource Key)

An ARK (Archival Resource Key) is a unique identifier used to reliably locate and access digital or physical resources, such as documents or collections, over time. Think of it as a persistent link or address that remains stable even if the resource moves or the hosting system changes. Developed by libraries and archives, ARKs help ensure long-term access to valuable information by providing a consistent way to identify and retrieve specific resources, supporting preservation and scholarly research.
