4.2 Identifying Digital Objects
4.2 Identifying Digital Objects
One of the major challenges facing the research and library communities today is how to establish the policies, infrastructure, and tools needed to create long-term persistent, accessible, and reusable digital data. Digital objects refer to files with metadata (including identifiers) that can be stored in and retrieved from a system, such as a digital repository. The identification of digital objects is important for discovery and access, provenance and assurance, reusability, and preservation of data. This chapter describes techniques that are being developed for identifying and managing all types of digital objects. After explaining how digital objects are managed, it discusses digital object identification and authentication and presents examples of digital object identifiers before concluding with a look at future bridges between digital and physical objects.
