Title: Identifiers.org and MIRIAM Registry: perennial identifiers for crossreferencing purposes
Abstract: Abstract The MIRIAM Registry provides unique, perennial and location independent identifiers for data used in the biomedical domain. At its core is a shared catalogue of data collections, for each of which a unique namespace is created, and extensive metadata recorded. This namespace allows the generation of Uniform Resource Identifiers (URIs) to uniquely identify any record in a collection. We present here the new Identifiers.org service which is built upon the information stored in the Registry and which provides directly resolvable identifiers, in the form of Uniform Resource Locators (URLs). The flexibility of the identification scheme and resolving system allows its use in many different fields, where unambiguous and perennial identification of data entities is necessary.
