In this 90-minute tutorial we will introduce you to ARKs (Archival Resource Keys), which can serve as persistent identifiers, or stable, trusted references for information objects (eg, web addresses that don't return 404 Page Not Found errors). In more than two decades, 8.2 billion ARKs have been created by over 1200 organizations — libraries, data centers, archives, museums, publishers, government agencies, and vendors. Highly flexible and non-paywalled, ARKs are adopted increasingly by organizations in the global South and by those that need large numbers of identifiers. With guided exercises, by the end of the session, participants will know when and how to create and manage ARKs. We will cover: Why ARKs non-paywalled, decentralized, flexibleUse cases Smithsonian, French National Library, Internet ArchiveMetadata for early and ongoing object developmentHow to get started fill out one formMinting and assigning ARK identifiersResolvers, resolution, redirectionPersistence considerations
