A Digital Object Identifier ("DOI") is an online cross-platform digital identifier of a object (such as a publication). It is unique and persistent in nature, functions as a permanent pointer to where the object is at any time (such as its URI within a publisher's or organization's database), and can be used to determine the object's usage and circulation status. The DOI system has obtained ISO certification as a digital environment identifier and interoperability standard (ISO 26324).

The Airiti DOI Registration Agency began operation in July 2011 as one of 10 RAs authorized by the （International DOI Foundation） worldwide. As Taiwan's only authorized DOI Registration Agency, the Airiti DOI RA provides professional DOI registration consultation in line with IDF policies and guidelines. It concatenates the resources of the Chinese-speaking academic community and collaborates with major DOI RAs around the world to facilitate the discovery and application of domestic research by overseas researchers.

The Airiti RA features a traditional Chinese character interface for registering the DOI of journals, conference papers, academic theses and dissertations, research reports, books, and online curricula, and is completely integrated with Airiti's digital publishing process. For example academic journals, pre-publication content, physical books or e-books included in the Airiti Library that are provided for simultaneous online release can be immediately registered and assigned a unique DOI. Once the Airiti RA issues a journal DOI and a range of suffix numbers, the registering organization can directly assign a unique DOI number per article or authorize the Airiti RA to do so. The Airiti RA interface allows registering organizations to verify the uniqueness and format compatibility of DOI numbers they assign to assure the quality and rigor of data.

Each RA has its own unique DOI prefix, and sends monthly resolution reports to determine usage and circulation rates. Please contact the Airiti RA for professional consultation provided by the RA regarding individual application for DOI registration and the requirements for DOI registration of other types of objects.

A key function of DOI registration via the Airiti RA is to then be able to connect the ORCID (Open Researchers and Contributor ID) of the object author with the title of the object for a full retrieval of relevant bibliographic records.

The Airiti RA service features a DOI metadata search engine, which can help find whether or not an application has been made for a certain reference at the Airiti RA or CrossRef DOI RA. a QR code generator by which a user can enter a DOI number and immediately convert it into a QR code for retrieval via mobile devices a DOI resolution engine to help resolve whether a DOI number is properly formatted and quickly test whether the DOI is effective, and to which RA it belongs.
