DOIidentifikaattorit, which translates to DOI identifiers, are persistent digital identifiers used to uniquely identify electronic documents or other digital objects. They are designed to provide a permanent and reliable way to locate and access these resources online, even if the underlying URL changes. A DOI is a string of characters that is registered with a DOI registration agency, such as Crossref or DataCite. This registration process ensures the identifier remains resolvable over time. When a DOI is created, it is linked to a specific digital object, and this link is maintained by the registration agency. If the location of the digital object changes, the metadata associated with the DOI can be updated to reflect the new location, ensuring that the identifier continues to point to the correct resource. This persistence is crucial for academic research, scientific publications, and any field that relies on the stable accessibility of digital information. The International DOI Foundation (IDF) oversees the DOI system, ensuring its global interoperability and adherence to standards. DOIs are typically presented as a character string starting with "10." followed by a prefix assigned to a registration agency and a suffix assigned by the registrant to identify the specific object. They are commonly used for journal articles, datasets, books, and other scholarly works, facilitating citation and discovery.
