This repository holds test details forked from the GeoSPARQL Compliance Benchmark at https://github.com/OpenLinkSoftware/GeoSPARQLBenchmark. The original repository holds far more tests and is run using the HOBBIT Platform. This subset is used with the modified Tests for Triplestore (TFT) platform.
The benchmark tests in this repository evaluate the GeoSPARQL compliance of RDF storage systems related to the Core, basic geometry, simple features and query rewrite aspects of the OGC GeoSPARQL standard. They cover requirements #1-4, 7-14, 19, 22 and 28 of the standard, and represent the capabilities relevant to Wikidata.
For reference, the data, queries and results from the src/main/resources directory of the original benchmark are reorganized in the geosparql directory below. Instead of having gsb_queries, _dataset and _answers directories to separate the files, the queries and answers are grouped together within the Core, Topology, Geometry Extension, Geometry Topology Extension and Query Rewrite (core, top, geoext, gtop and qrw) folders. In addition, only the dataset.rdf file is used and is also included in each of the folders.
The specific requirments and queries used in this repository are:
