fielduse

Fielduse is a term used in data governance and information management to describe how each field in a dataset—such as a database column, a spreadsheet column, or a form element—is intended to be used. It captures the purpose, constraints, and context for a field to aid in data quality, interoperability, and compliance.

The concept helps teams document the intended use of data elements beyond their technical data type. Key components often included in a fielduse record are the field name, data type, allowed values or ranges, validation rules, default values, and a concise description of the field’s purpose. Additional attributes may cover provenance, privacy level or sensitivity, retention requirements, and access or usage restrictions. Collectively, these details support consistent data entry, transformation, and consumption across systems.

Fielduse supports several outcomes. It improves data quality by clarifying valid use and reducing ambiguity; it enhances data cataloging and discovery, making it easier for analysts and developers to understand and reuse fields; it aids integration by aligning field meanings across databases and APIs; and it supports regulatory compliance by identifying sensitive data and appropriate handling.

Common contexts for fielduse include data dictionaries, metadata repositories, ETL pipelines, API schemas, and form design documentation. Example entries might label an email field as used for verification and transactional notices only, with privacy restrictions applied and a recommended retention period.
