Metadata fit for the purpose of semantic annotation and semantic search

The HealthDCAT-AP introduces new properties that rely on ontologies or controlled vocabularies, reinforcing the use of URIs and RDF to ensure consistent description of health datasets, which is crucial for interoperability.

 
 
These new properties enhance the semantic annotation, ensuring that metadata can accurately describe health datasets. The enhanced semantic annotations in HealthDCAT-AP also support advanced search capabilities, making it easier to retrieve relevant data through more precise SPARQL queries.

  • New HealthDCAT-AP properties enhancing semantic annotation include:
  • healthdcatap:healthCategory (Controlled vocabulary)
  • healthdcatap:publisherType (Controlled vocabulary)
  • healthdcatap:healthTheme (Wikidata)
  • healthdcatap:hasCodingSystem (Wikidata)
  • healthdcatap:hasCodeValues (Wikidata associated with external standards like ICD-10)
  • dpv:hasPersonalData (Personal Data Categories (PD) of the DPV ontology)

For the DCAT-AP property dct:conformsTo, the Wikidata URIs MUST also be used.
