A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). [2] DOIs are an implementation of the Handle System ; [ 3 ] [ 4 ] they also fit within the URI system ( Uniform Resource Identifier ).
A digital object identifier (DOI) is a unique persistent identifier to a published work, similar in concept to an ISBN. Wikipedia supports the use of DOI to link to published content. Where a journal source has a DOI, it is good practice to use it, in the same way as it is good practice to use ISBN references for book sources.
In computing, object identifiers or OIDs are an identifier mechanism standardized by the International Telecommunication Union (ITU) and ISO/IEC for naming any object, concept, or "thing" with a globally unambiguous persistent name.
Major publishers use the Handle System for persistent identification of commercially traded and Open Access content through its implementation with the Digital Object Identifier (DOI) system. The number of prefixes, which allow users to assign handles, is growing and stands at over 12,000 as of early 2014.
A good example of metadata is the cataloging system found in libraries, which records for example the author, title, subject, and location on the shelf of a resource. Another is software system knowledge extraction of software objects such as data flows, control flows, call maps, architectures, business rules, business terms, and database schemas.

The same identifier can be independently defined in multiple namespaces. That is, an identifier defined in one namespace may or may not have the same meaning as the same identifier defined in another namespace. Languages that support namespaces specify the rules that determine to which namespace an identifier (not its definition) belongs. [10]
In digital object architecture, a digital object has a machine and platform independent structure that allows it to be identified, accessed and protected, as appropriate. A digital object may incorporate not only informational elements, i.e., a digitized version of a paper, movie or sound recording, but also the unique identifier of the digital ...
