Find in Library

This article will provide a brief overview of considerations made by the UTSC Library in selecting a persistent identifier scheme for digital collections in a mid-sized Canadian library.  ARKs were selected for their early support of digital object management, the low-cost, decentralized capabilities of the ARK system, and the usefulness of ARK URLs during system migration projects.  In the absence of a subscription to a centralized resolver service for ARKs, the UTSC Library Digital Scholarship Unit built an open source PHP-based application for minting, binding, managing, and tracking ARK IDs. This article will introduce the application's architecture and affordances, which may be useful to others in the library community with similar use cases, as well as the approach to using ARKs planned for an Islandora 2.x system.
