Summary Report on the RDF Template for the QUANTUM DQ&U Label

Executive Summary This report proposes the initial RDF template for the QUANTUM Data Quality, Utility and Maturity (DQ&U&M) label, providing practical examples of its implementation. The template provides a machine-readable representation of dataset-level quality assessments, using established W3C standards such as DCAT, DQV, SKOS, Open Annotation and PROV-O, extended through the custom QUANTUM qnt vocabulary. It specifies what to represent: catalogues and datasets, aggregated quality certification through dqv:QualityCertificate, dimension-level quality measurements through dqv:QualityMeasurement, QUANTUM quality categories and dimensions, and star-based label outputs. It also defines how maturity is represented, not as a single organisation-wide score, but as the maturity of specific Data Governance Workflows associated with a Data Holder. The model keeps DQ&U and maturity as independent assessments, while allowing them to be linked in a single exported RDF label. It also anticipates future extensions, including Fitness-for-Purpose feedback through dqv:UserQualityFeedback, provisional assessment status, and provenance metadata documenting generation by the QUANTUM Labelling Tool. Overall, the template provides a reusable semantic structure for representing QUANTUM labels in an interoperable and extensible way, while leaving room for future validation, certification and alignment with HealthData@EU.
