      The URI namespace of all resources managed by Cortex.

    • PROVENANCE

      public static final org.apache.jena.rdf.model.Resource PROVENANCE
      The named graph holding per-statement provenance within the assertions dataset.

    • USAGE

      public static final org.apache.jena.rdf.model.Resource USAGE
      The named graph holding per-resource view counts within the assertions dataset.

      Like PROVENANCE this is a reserved graph, not a branch and not part of the approved assertions: it records how the graph is used rather than what it claims.

    • VIEW_COUNT

      public static final org.apache.jena.rdf.model.Property VIEW_COUNT
      The property recording a resource's time-decayed view score, within USAGE.

      Not a plain tally: the value is discounted towards zero as it ages, so it is only meaningful alongside VIEW_COUNT_UPDATED, which says when it was last brought up to date.

    • VIEW_COUNT_UPDATED

      public static final org.apache.jena.rdf.model.Property VIEW_COUNT_UPDATED
      The instant VIEW_COUNT was last recomputed, within USAGE.
