    01In brief

    The short answer.

    The Nexus cycle in Nexus Registry is the eight-step path by which a question in the governance and institutions field becomes evidence, a Foundry build, an organized community, a controlled test, a publication and a decision taken by the competent authority. Here the evidence step rests on data engineering, interoperability and stewardship as well as digital identity and public digital systems, and findings feed Methods and Technical.

    Scoping to review.

    Canvas · scoping to reviewDesign, not a record
    How work moves in this field: an exercise from design to lessonsObjectives and a scenario are designed with the owner; injects are scripted; players respond in cells while controllers and observers watch; a hot wash and an after-action report turn observations into owned improvements. Design of the process, not a record of a run.

    03Geography

    People and exposure in World.

    For how work moves in this field, in GCRI's spatial-intelligence reading, the map opens on population density, true-colour imagery and night lights, framed on World; every other NASA layer, live feed and forecast waits in the layer list.

    The interactive map needs JavaScript; the layer list and sources are below.

    05The cycle here

    How the Nexus cycle runs for registry.

    In Nexus Registry the cycle is about records: every question, evidence set, build, test, publication and decision in the other platforms leaves an identified, versioned record here, which is what makes the renew step possible.

    TermDefinition
    Nexus cycleThe eight-step loop by which work moves in every Nexus field: question, evidence, build, organize, test, publish, decide and renew, each step with a named owner.
    Competent authorityThe body that a law or regulation designates to exercise a given power or duty, such as a supervisor, a civil protection agency or a ministry; only it can take the decisions the law assigns to it.
    Peer reviewEvaluation of a work by independent experts in the field before publication.
    VersioningKeeping each changed state of a record as a distinct, dated version linked to the ones before and after it.
