ISO standard unique string identifier for a digital object
AI overview
A digital object identifier (DOI) is a unique code assigned to digital content—like research papers, datasets, or other online materials—that serves as a permanent web address for finding that specific item. This system matters because it provides a stable, standardized way to locate and cite digital works, even if the content moves to a different website or URL.

Article
A digital object identifier (DOI) is a persistent identifier, or persistent handle, used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system (Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications.
A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model to represent metadata.
