Definition: Data & Data Instances Enablers ABB is a Grouping that refers to a set of Data Objects representing structured data artefacts and specialised forms of data that are produced, managed, exchanged or consumed within digital public services. It includes datasets, master data, reference data, controlled vocabularies, metadata and other specialised data forms that materialise semantic specifications and support interoperability. Source: Inspired by European interoperability and data governance practices.

These data artefacts instantiate semantic specifications and provide the concrete values, identifiers, classifications and contextual descriptions required for meaningful data exchange and reuse. By structuring different categories of data (e.g., master data, reference data, controlled vocabularies), this grouping enables consistency, traceability and trust in cross-border and cross-domain digital interactions.
