Identifiers.org is a project providing stable and perennial identifiers for data records used in the Life Sciences.
It is also a resolving system that relies on collections listed in the MIRIAM Registry to provide direct access to different instances of the identified records.
An Identifiers.org URI is formed of several parts: The system allows a consistent and uniform annotation of datasets.
Identifiers.org URIs are used to encode the metadata in the standard formats of the COMBINE initiative,[4] such as SBML.
Identifiers.org URIs are similar to PURLs, albeit providing alternative resolutions for collections with several instances.
