Unreleased

3.0.0 (2026-09-23)

Breaking: metrics v2, not compatible with v1 metrics. Evaluation is driven by the shared piveau-utils metric-definition vocabulary and writes boolean dqv:value measurements into a metrics graph marked dct:conformsTo <https://piveau.eu/ns/metrics/2.0.0>; the v1 star scheme and catalogues are removed. Requires score 4.0.0, which must be deployed first.

Updated:

• piveau utils was updated to v 12.0.17 to fix a typo in the EUROVOC vocabulary, see piveau-utils changelog
  

Added:

• Write dqv:hasQualityMetadata on every evaluated entity, not just the dataset. createMetricsGraph anchors only the dataset, leaving distributions and data services with no direct link to the graph holding their own measurements — a consumer had to reach them by traversing the owning dataset. Against a large triplestore that traversal leaves the entity unbound in SPARQL, which is what pushes scope-limited metric queries past Virtuoso's cost-estimation limit (piveau-metrics-cache refresh). Blank-node entities are skipped, having no stable identity to anchor; the write is guarded so re-annotation does not duplicate it. Applies to newly annotated data — existing metrics graphs need re-annotation. See docs/DATA-CONTRACT.adoc.
  

Fixed:

• Skip a dcat:accessService target that the payload does not describe as a data service — either a bare IRI reference carrying no triples at all, or a resource without the rdf:type dcat:DataService that DCAT-AP requires. Such a resource was previously evaluated against all 18 dcat:DataService bindings, failing every one of them; the false negatives added a phantom entity to the catalogue's data-service count and coverage and pulled a 0.0 group into the dataset-final roll-up (observed: a dataset dropping from 6.875 to 4.583). No measurement is now written, so the resource reaches neither the score service nor the cache. The dcat:distribution edge is unchanged — untyped distributions are common in real data and remain evaluated. See docs/DATA-CONTRACT.adoc.
  

Changed:

• Use org.apache.jena.vocabulary.DCAT for the core dcat: traversal terms instead of hand-rolled namespace constants; AnnotatorVocab is removed. VERSION_IRI and ADMS_DEPRECATED (an ADMS status value, now built from ADMS.NS_SCHEME_STATUS) move to JobRunner. No behaviour change. See docs/ADR-007-rdf-vocabulary-source.adoc.
  
• v2 rewrite: data-driven metric evaluation against a shared piveau-utils vocabulary (MetricDefinitions), boolean-only DQV measurements, a dct:conformsTo version marker on the metrics graph, and deprecated-distribution handling (all-deprecated datasets are skipped, not forwarded). See docs/DATA-CONTRACT.adoc.
