What it is

Reference data management (RDM) governs the shared code sets that every other system depends on. When those lists drift apart, reports stop reconciling and integrations break. NexusGreenData holds one authoritative, versioned copy of each list.

It is paired with the master data management module and runs on the same data catalog, so reference values and master records share one governed vocabulary.

What it does

Controlled lists that stay consistent

01

Code sets and values

Define each controlled list once, with bilingual labels, descriptions and ownership, and reuse it everywhere.

02

Versions

Every change produces a new, dated version. You can see what a code set looked like at any point and roll back if needed.

03

Hierarchies

Roll values up into parent-child structures so a region, a group or a category can be summarised consistently.

04

Crosswalks

Map one code set to another to reconcile systems or standards that use different codes for the same concept.

05

Governed change requests

Changes flow through an approval queue with rejection, resubmission and notifications — never a silent edit in production.

06

Glossary sync and import/export

Two-way sync with business glossary terms, plus CSV and JSON import and export for bulk loads and downstream use.

How it works

Create a code set, add its values with bilingual labels, and publish a version. From then on, every edit is a change request routed to an approver, so the published list is always the approved one.

Code sets sync to business glossary terms and can be imported or exported as CSV or JSON, so the same controlled vocabulary reaches every tool and pipeline.

Who it is for

When lists no longer agree

Integration and BI teams

Teams whose dashboards and pipelines break because the same status or country code means different things in different systems.

Data governance offices

Offices that must prove a controlled, versioned, auditable vocabulary across the organisation under NDMO standards.

Standards and compliance owners

Owners who need crosswalks between internal codes and national or international standards without rekeying.

FAQ

Reference data management — frequently asked questions

What is reference data?

Reference data is the controlled lists and code sets that classify everything else — country codes, currencies, status values, organisational units. Reference data management keeps those lists consistent, versioned and governed across systems.

How are changes controlled?

Every change goes through a change request with an approval queue. Requests can be rejected and resubmitted, and approvers are notified, so a code set is never edited silently in production.

Does it sync to the data catalog?

Yes. Code sets are synced with business glossary terms, so the same controlled vocabulary is visible wherever your teams work with data.

Can we map between two code sets?

Yes. Crosswalks map one code set to another, and hierarchies roll values up into parent-child structures — useful when systems or standards use different codes for the same concept.

One source of truth for every code set.
