💡 Why DisSModel? Reproducible, interoperable, and cloud-ready geospatial modeling — designed for the next generation of environmental simulations.
Open tools for Geospatial Linked Data, semantic integration, and reproducible geoinformatics.
| Repository | Purpose | Tech Stack |
|---|---|---|
| qgissparql | Bridge QGIS layers with SPARQL endpoints for semantic querying | Python, QGIS, RDFLib |
| rdfmapper | Declarative Object-RDF mapper for Python (like SQLAlchemy for Linked Data) | Python, RDF, SPARQL |
| DBCells | Publish spatial modeling outputs as Linked Open Data (LOD) | Python, RDF, Flask |
🔗 Research Focus: Interoperability between traditional GIS and Semantic Web standards (RDF, OWL, SPARQL).
Compiler courses & polyglot implementations
I develop educational compiler/interpreter projects (Nand2Tetris, Crafting Interpreters) as pedagogical tools for Computer Science education.
