Every record carries rights: who owns the content, under what licence it may be reused, who may see it and when it may be withdrawn. Openness serves verification and reuse, but some records hold personal, sensitive, culturally protected or commercially restricted information. This page sets out how licences, access classes, embargoes and withdrawals are recorded, where they conflict, and what rights holders and reviewers need before a record is disclosed to a wider audience.
GCRI · Established · service level R0
Data licences state on what terms a record may be reused; with access classes, embargoes and withdrawal rules they decide who may see a record and when. Openness serves verification and reuse, while some records hold personal, sensitive, culturally protected or commercially restricted information that needs review before wider release.
For rights and disclosure, in GCRI's spatial-intelligence reading, the map opens on true-colour imagery, population density and night lights with true colour from NASA GIBS, framed on World; every other NASA layer, live feed and forecast waits in the layer list.

Publication rights, withdrawal and audience. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
A record has no licence, a licence in prose only, or one licence on the landing page and another in the metadata. Careful reusers avoid it, careless ones reuse it wrongly, and holders cannot enforce terms that were never stated clearly.
A record meant for a programme team is exported, cached or indexed alongside public ones. Restricted fields appear in search results or partner copies, and once harvested the disclosure cannot be reversed.
Embargo end dates are recorded but not enforced, or enforced but not recorded. Content is released early against agreements, or stays closed long after obligations end, defeating the openness that funders require.
A rights holder asks for removal while the scholarly record calls for persistence. Erasure rights, takedown notices and retraction norms pull in different directions, and an unrecorded removal leaves citations pointing at nothing.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Machine-readable licence | A licence expressed in a standard identifier or vocabulary, such as SPDX or a Creative Commons URL, that software can read. |
| Embargo | A set period during which a record is withheld from a wider audience before release. |
| Access class | A category that sets which audience may see a record, from public to restricted. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Records with a machine-readable licence | share of records | monthly | Licence metadata | OBSERVED |
| Records with an access class | share of records | monthly | Schema validation | OBSERVED |
| Licence conflicts between metadata and landing page | count | quarterly | Sampled comparison | OBSERVED |
| Embargoes past their end date and unreleased | count | weekly | Embargo register | OBSERVED |
| Withdrawal and takedown requests | count by stated ground | quarterly | Case records | REPORTED |
| Time to act on a takedown request | days | per case | Case records | OBSERVED |
| Disclosure reviews completed before wider release | share of releases | monthly | Review records | OBSERVED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.
Fig. 02Nodes carry their type, two metric rows and a state; connectors show what feeds what; dashed frames name the owners; the timeline is the cadence. Design of the pipeline, not a record of a run.
Named public datasets and institutional records, each with its licence class. Sources by agreement are used only under their terms and never republished.

Nexus Registry prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Rights holders and authors | Under which licence and to which audience a record may be released | Funder requirements, publisher policies and the record's sensitive fields |
| Data protection officers | Whether personal data in a record may be disclosed, restricted or erased | Access class, lawful basis, retention and the public interest in a persistent record |
| Indigenous data governance bodies | Whether and how community data or knowledge may be shared | CARE principles, Local Contexts labels and the community's recorded terms |
| Platform publishers and repository managers | Whether to act on a takedown or withdrawal request | The request's grounds, the rights record and the policy for leaving a tombstone |
Disclosure risk is cumulative. A record that is harmless alone can identify a person or a vulnerable site when combined with others, which is why statistical agencies apply disclosure control before releasing data. Rights are also layered: an author may hold copyright, a funder may require open access, a community may hold collective rights over traditional knowledge, and a data subject holds privacy rights that override both.
Research data communities summarize the aim as findable, accessible, interoperable and reusable, while principles for Indigenous data governance add collective benefit, authority to control, responsibility and ethics. The Registry's three classes, public, restricted and protected, are described on rights and visibility.
Each record receives a visibility class and licence before release, decided by its owner within the law.
Restricted records are visible only to people authorized for a purpose, enforced with access controls from cybersecurity and cryptography.
Withdrawal removes a record from public view; its identifier resolves to a notice with the date and any replacement.
Nothing published can be fully recalled. Disclosure judgements involve values as well as rules, and re-identification risk changes as other data becomes available.
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.
