Identification of data entities using Compact Identifiers

Compact Identifiers syntax

A Compact Identifier is a unique string consisting of a Prefix (assigned by curator), a colon (‘:’), and an Accession (e.g. local identifier string). The Prefix is composed of an optional Provider Code, and an assigned Namespace, separated by a slash (‘/’).

Examples

identifiers.org URL syntax

The URL for uniquely linking to data entities is written in the following form:

https://identifiers.org/[provider_code/]namespace:accession

The optional parameter provider_code denotes the Provider Code part of the Prefix. It is trailed by a slash, to separate it from the required namespace , which is followed by a colon and the accession.
