This report (FAIRagro Milestone M3.3.3) defines exemplary data-fitness elements that can be reused to build FAIRness measurement templates, with “data fitness” understood as how well data meet the needs of a specific scientific/analytical use case. It proposes a reusable, explicitly non-operational method that bridges (1) producer-side, standards-based data quality concepts grounded in ISO 19157 and (2) user-side, fitness-for-purpose requirements extracted from domain literature. The result is an integrated, machine-readable conceptual framework (illustrated via a digital soil mapping use case) intended to support subsequent FAIRagro work on operationalization, community refinement, and implementation of application-specific data quality queries, without prescribing metrics or running assessments itself.
