Analysis of DOI names
DOI (Digital Object Identifier) is a digital identifier used to uniquely identify digital resources, such as articles, books, pictures, etc. It consists of numbers and letters, usually starting with 10., such as 10.1000/182. DOI names help people find and cite digital resources more easily because they are unique and immune to changes in URLs. In academic research, DOI names have become one of the standard ways to cite documents.
The meaning of a DOI name can be understood through its structure. In general, a DOI name consists of two parts: a prefix and a suffix.
The prefix is composed of numbers and periods, and usually starts with 10., such as 10.1000/182. This prefix indicates which DOI registration authority this identifier belongs to. Internationally, common DOI registries include Crossref, DataCite, mEDRA, etc. Different DOI registries may have different prefixes, but they all start with 10.
The suffix is composed of numbers and slashes, such as 182 in 10.1000/182. This suffix is assigned by the DOI registration authority and is used to uniquely identify a certain digital resource. Generally speaking, the length of the suffix is not fixed and can be any length.
Therefore, through the prefix and suffix of the DOI name, we can know which DOI registration agency the DOI name belongs to and which digital resource it identifies. That's why DOI names can help people find and cite digital resources more easily.
