Concepts → Metadata Precedence

Incorta Nexus follows a defined order of precedence when multiple sources provide information about a column.

Order of precedence

Nexus processes column metadata and evaluates available metadata sources according to the following order of precedence:

  1. Business View column description: User-provided description.
  2. Metadata Tune: Automatically generated metadata.
  3. AI Container instructions: Instructions provided for an AI Container, if applicable.

Metadata Tune also considers the existing Business View column description when generating metadata. If the description provides sufficient context, Metadata Tune uses it instead of generating new metadata.

For more information, refer to Incorta Nexus Metadata Tune.

Example

Consider a Customer Health Score column that rates customer health from 0 to 100:

  • Business View column: 0 = Low customer satisfaction; 100 = High customer satisfaction
  • Metadata Tune: Customer Health Score measures customer satisfaction on a scale from 0 to 100 and can be used to identify accounts with lower or higher levels of customer satisfaction.
  • AI Container instruction: Percentile rank of customer satisfaction

If a user asks: “Show me the highest-performing customer accounts this year.”

Nexus uses the Business View column description to interpret the Customer Health Score because it takes precedence over the Metadata Tune output and AI Container instructions. Therefore, Nexus interprets higher Customer Health Score values as indicating higher customer satisfaction and returns the accounts with the highest scores.

If you modify a Business View column description after Metadata Tune has generated metadata, the updated Business View description takes precedence. The previously tuned metadata is invalidated and is no longer considered.

Important
  • If you modify a Business View metadata after Metadata Tune has generated its metadata, the previously generated Metadata Tune value is invalidated. The system uses the updated Business View column description instead.
  • If you edit a Metadata Tune value, the edited value is automatically locked and is preserved in subsequent automatic enrichment cycles.
  • To permanently override tuned metadata, update the Business View column description directly.
