DIGITAL OBJECT IDENTIFIERS (DOIs®)
Each paper published in an AIAA journal is assigned a DOI® number, which appears beneath the author's affiliation in the published paper.
A DOI (Digital Object Identifier) is an identifier of intellectual property entities on digital networks. It provides a system for persistent identification and interoperable exchange of managed information. The DOI system is administered by the International DOI Foundation www.doi.org, a not-for-profit organization. Another not-for-profit organization, CrossRef www.crossref.org, uses the DOI as a reference-linking standard that enables cross-publisher linking; CrossRef maintains the lookup system for DOIs. The use of DOIs as identifiers makes the management of intellectual property in a networked environment easy and convenient and allows the construction of automated services and transactions.
The DOI has two components: a prefix (before the slash) and a suffix (after the slash). The prefix is a DOI resolver server identifier (10), followed by a period, plus a unique identifier assigned to the publisher (2514 for AIAA). The suffix is an arbitrary number assigned by the publisher. An example of an AIAA DOI might be 10.2514/1.12345. Each DOI is registered in a central resolution database that associates it with one or more corresponding Web locations (URLs).
Once a DOI number is assigned, it cannot be altered, and it remains persistent regardless of possible future publisher or organization changes.
DOIs from other papers may be embedded into the linking coding of an AIAA paper's reference section. When a linked reference is clicked, it opens another browser window leading to the entrance page or abstract of the referenced paper. This is the service provided by CrossRef (see above). Because the use of the DOI system is rapidly becoming a standard in scholarly publishing, an increasing number of references can be located through this linking capability.
