Lightweight and friendly .NET library for realizing modern Semantic Web applications (RDF, SPARQL, SHACL)
A highly scalable RDF triple store with full-text and GeoSPARQL support
PurRDF — one RDF 1.2 engine, one behavior, in Rust, Python, WebAssembly and C. Deterministic BM25 full-text search, exact GeoSPARQL 1.1 and embedding kNN answered from SPARQL, in-process, over one dataset: the three jobs a triple store usually kept PostgreSQL beside it for. Plus native codecs, RDFC-1.0, SHACL, ShEx, entailment and GTS transport.
Strabon is a fully implemented semantic geospatial database system that can be used to store linked geospatial data expressed in RDF and query them using an extension of SPARQL.
Crowdsourced geospatial question-answering dataset. Published in ISWC 2023 as "Benchmarking Geospatial Question Answering Engines using the Dataset GeoQuestions1089".
Non-official Fuseki Docker image with GeoSPARQL support
Map4RDF allows visualising and interacting with Linked Geospatial Data available in any SPARQL endpoint
DLMAPS = Description Logic Maps: Ontology-Based Spatial Queries to Digital City Maps
Spatial data management with semantic web technology and Linked Open Data (LOD)
GeoSPARQL Compliance Benchmark integrated into the HOBBIT Platform
Generate RDF out of a GeoPackage
Generate a spatial index file from a TDB2 dataset
Apache Jena Fuseki with built-in GeoSPARQL support, enabling spatial queries on RDF data.
Modal spatiotemporal semantics for executable knowledge graphs
GeoRDFBench Framework: Geospatial Semantic Benchmarking Simplified
A QGIS plugin to export vector layers to RDF Triples, supporting OGC GeoSPARQL and the DBCells Land Use and Cover Change (LUCC) ontology.
Compares VKG approach against PostgreSQL + REST API for cloud-native geospatial data integration. Federates Sentinel-2 COGs (raster) and Overture Maps GeoParquet (vector) via DuckDB FDW, PostGIS, and PL/Python. Evaluates two raster integration strategies, and SPARQL (Ontop VKG) vs REST API (pg_featureserv) trade-offs. Fully Dockerised.
A QGIS plugin to import Linked Data from SPARQL endpoints and Data.world, transforming RDF triples into native geospatial layers.
