EZID: Easy dataset identification & management
Joan Starr, Manager, Strategic and Project Planning and EZID Service Manager, California Digital Library

Data and data curation are assuming a growing role today’s research library. New approaches are needed both to address the resulting challenges and take advantage of the emerging opportunities. Long-term identifiers represent one such tool. In this presentation, Joan Starr will introduce identifiers and an application designed to make them easy to create and manage: EZID. She will provide a closer look at two identifier types: DOIs and ARKs, and discuss what bringing an identifier service to your institution might mean.

  15. 15. EZID: long-term identifiers made easy take control of the management anddistribution of your research, share and get credit for it, and build your reputation through its collection and documentation Primary Functions 1. Create long-term identifiers 2. Manage identifiers over time 3. Manage associated metadata over time
