Digital Object Identifier
A Digital Object Identifier (DOI) is a persistent identifier used to uniquely and permanently identify digital objects, such as academic papers, datasets, and other scholarly works. It provides a stable link to the object's location online, even if the URL changes, ensuring long-term accessibility and citation reliability. DOIs are managed by registration agencies and follow the ISO 26324 standard.
Developers should learn about DOI assignment when building or maintaining systems for academic publishing, research repositories, or digital libraries to ensure proper citation and archiving of scholarly content. It is crucial for implementing metadata standards, integrating with citation databases like Crossref, and enhancing the discoverability and permanence of digital assets in scientific and educational platforms.
