The international DOI foundation is a non-profit organization established in 1998. It is the management organization of DOI system, and its purpose is to protect the intellectual property rights related to DOI system, popularize the application of DOI, and ensure that all the improvements of DOI system (such as creation, maintenance, registration, analysis and related decisions) can be used by all registrants.
DOI system was officially released as an ISO international standard in 20 12, and became a global standard for identifying and linking digital resources.
Digital Object Identifier (DOI) is a set of mechanisms to identify digital resources, including videos, reports or books.
It has both a mechanism for naming resources and a protocol for resolving identification numbers into specific addresses. The motivation of developing DOI is to supplement the shortage of URI, because on the one hand, the URL referred to by URI often changes, on the other hand, URI actually expresses the location of resources (that is, websites), rather than the information of digital resources themselves. DOI can overcome these two problems.
After the DOI identification number is parsed, it can be connected to one or more data. However, the identification number itself has nothing to do with the data after parsing, so it may be that all the data can not be obtained, but only the information of relevant publications can be obtained.
The parsing protocol of DOI can be found in RFC 3652. RFC 365 1 describes the naming mechanism and RFC 3650 describes its architecture.
DOI analyzes the identification number through Handle system, but in practical application, it is mostly through web analytics. For example, if you connect to http://dx.doi.org/10.1007/s00223-003-0070-0, you can see the information or full text of the paper, and the corresponding identification number is10.1007/s00222.
