Nexus Registry is the platform of The Global Centre for Risk and Innovation (GCRI) for public-safe records of programmes, evidence, publication status and correction histories, subject to owner authority. Records are useful only if others can cite and reuse them reliably. This page describes the stable references and permitted interfaces the Registry is designed to offer, and publishes each interface and its documentation as it is released. No interface is shown as available until it is released. The current service level is R0: information and enquiries.

Nexus Registry interfaces are the stable references and permitted machine interfaces through which others can cite and reuse released records. Each interface and its documentation is published only when it is released, with its version and terms of use; until then none is shown as available.
The jurisdictions that hold authority over this question: countries, their first-level divisions and capitals, shown for West Africa as an example geography for this subject.
Each record has one identifier that is never reused, even if the record is withdrawn.
The identifier resolves to the record's public page, or to a notice explaining why it is no longer shown.
Citations can point to the current version or to a specific earlier one.
Retrieval of released public records and their metadata, never restricted or protected records.
Machine-readable exports in open formats, such as JSON-LD and the Data Catalog Vocabulary (DCAT), with provenance in W3C PROV.
Notices when a record is corrected, superseded or withdrawn, so copies elsewhere can be updated.
Each field's meaning, allowed values and version, published with the interface.
Interfaces and their documentation will be listed here as each is released, with its version and terms of use. Until then, records can only be cited by their public pages, once public records are released. Technical interfaces across Nexus Foundry are described on developers and integrations.
Reusing a record through an interface carries its rights and limits with it. Interface access confers no authority, endorsement or certification.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Persistent identifier | A long-lasting reference to a digital object, person or organisation, such as a DOI, ORCID iD or ROR ID, that resolves even when locations change. |
| Interoperability | The ability of health information systems to exchange data and use it with the same meaning, using standards such as HL7 FHIR. |
| DCAT | The W3C Data Catalog Vocabulary for describing datasets and data services in catalogues. |
Registries held by statistics offices, libraries, research funders and programme partners keep their own authority. The Nexus Registry is designed to link to their records by reference rather than copying them, with aliases preserved so an external identifier still resolves.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
