Summary
This PR implements additional metadata fields across various RDF entities to enhance alignment with DCAT and provenance/quality standards. The changes improve semantic expressiveness and interoperability across datasets, catalogues, and data services.
✅ Implemented Fields
Agent
Added support for describing agents (e.g., publishers, creators, data providers).
Spatial
Included dct:spatial to indicate the geographic coverage of datasets and services.
Dataset
Enriched with:
prov:wasGeneratedBy: traces back to the activity or process that generated the dataset.
dqv:hasQualityAnnotation: links to a quality annotation to describe quality metrics or standards.
prov:qualifiedAttribution: provides detailed attribution including the responsible agent and role.
Catalog
Support added for:
foaf:homepage: to represent the catalog's homepage URL.
Distribution
Added:
dct:retentionPeriod: defines how long the distribution is retained.
dct:temporalResolution: captures the granularity of the temporal dimension.
DataService
Implemented core structure and verified alignment using the Excel specification ("Check excel").
🔧 Notes
All newly introduced fields were verified against the controlled vocabulary and shape expectations from the GDI metadata model and SHACL definitions.
The update ensures these fields are parsed, serialized, and available in the RDF export and/or API layer as appropriate.
