# Golden record

The golden record is the canonical profile produced by [Profile Resolution](/identity-resolution/profile-resolution.md). It contains one row per [`dinmo_id`](/identity-resolution/dinmo-id.md).

Use the golden record when you need a trusted, deduplicated profile table for Customer Hub, Segments, Activations, analytics, or downstream models.

## What the golden record contains

The golden record can include:

* `dinmo_id`, the resolved profile ID
* `last_updated_at`, the latest update timestamp for the resolved profile
* selected identifiers, such as email, phone, user ID, or customer ID
* selected model fields, such as country, consent status, signup date, or last login date

The physical output is exposed in `identity_golden`. See [Output tables](/identity-resolution/profile-resolution/output-tables.md#identity_golden) for the table reference.

## How values are selected

When multiple source records merge into the same profile, DinMo needs to choose one value for each golden field.

This is handled through [survivorship rules](/identity-resolution/survivorship-rules.md), such as:

* Last non null
* Most frequent
* Model Priority Order

## Recommended first fields

Start with fields that are useful and easy to validate:

* email
* phone number
* user ID or customer ID
* country
* consent or subscription status
* signup date or last login date

Keep the first golden record focused. A smaller table is easier to review before activation.

## Validate the golden record

Before using the golden record downstream, validate:

* profile count
* identifier completeness
* high-impact fields such as email and consent
* sample profiles from important matching rules

See [Review and monitor](/identity-resolution/profile-resolution/review-and-monitor.md) for the validation workflow.
