External Apache Jena GeoSPARQL agreement

This experiment evaluates a PULSE-projected CRS84 Point/Polygon graph with the unmodified Apache Jena GeoSPARQL 6.1.0 query engine. The containerized Java harness is in external/jena-geosparql and imports no PULSE geometry code.

Protocol:

  1. Select the 86 checked-in CRS84 topology cases.
  2. Materialize every case point as an instance and every case polygon as a region in one GeoSPARQL graph.
  3. Query the full 86 x 86 cross product with geof:sfWithin, geof:sfIntersects, geof:sfDisjoint, and geof:sfTouches.
  4. Compare all 7,396 returned rows with PULSE strict-inside, boundary-inclusive membership, disjointness, and boundary results.
  5. Report projection, container, RDF load, and query-materialization timings separately.

Run from the repository root:

docker build --quiet -t pulse-jena-geosparql:6.1.0 external/jena-geosparql
python -m pulse_spatial.experiments.geosparql_external `
  --require-parity `
  --output-json experiments/geosparql-external/results/jena-topology.json `
  --output-markdown experiments/geosparql-external/results/jena-topology.md

This is a focused external-system agreement test, not an OGC conformance suite and not a like-for-like throughput comparison between a native event runtime and a triplestore.
