Identifiers.org

Identifiers.org is a system providing resolvable persistent URIs used to identify data for the scientific community, with a current focus on the Life Sciences domain. The provision of a resolvable identifiers (URLs) fits well with the Semantic Web vision, and the Linked Data initiative.

Key facts

  • resolvable identifiers: the system provides resolvable identifiers in the form of URIs
  • location independent: the system decouples the identification of records from the physical locations on the web where they can be retrieved
  • free to use: there is no cost involved to register or use the identifiers or this facility
  • granularity of identifiers: identifiers available at multiple levels (data collections, resources and data entities)
  • customisable behaviours: the system can be tailored to needs in terms of formats available and preferred resolving locations
  • RDF support: responses encoded in RDF/XML are provided via content negotiation, other formats may be added as requested
  • community driven: we rely upon the community to drive and direct development, as well as to contribute new data collections
  • curated resource: there is dedicated manpower to ensure that information in the Registry remains up-to-date and accurate
  • reliable: there is an automatic monitoring system to check registered resources and forewarn curators
  • unrestricted scope: currently focused on Life Sciences, but the scope is potentially unlimited (community feedback dependent)
  • ...

Resolving mechanism

Identifiers.org provides direct access to the identified data using one chosen physical location (or resource). If more than one physical locations providing the data are recorded in the Registry, then you can access them via the top banner or by using a profile.

Relationship to MIRIAM Registry

Identifiers.org is an additional layer built upon the information stored in MIRIAM Registry. The Registry provides the necessary information to allow users to generate unique, perennial and unambiguous identifiers for scientific data.

Identifiers.org provides resolving services for handling those resolvable identifiers, allowing them to be directly used within a Web browser.

The content of the Registry is open to community contributions, therefore new submissions and corrections are strongly encouraged.

Improved service performance and reliability through deployment in two redundant EBI Data centres located in London.
Feb 2014
Updated interface, which reorganise and simplify access to the information provided by the website.
Feb 2014
A new resolving mechanism has been implemented for canonical Identifiers.org URIs, which allows direct access to the identified data, using a chosen physical location. A banner is available for accessing other resources.
