 ## Files

+* `/rdf` - the final RDF files.
+* `/ontology` - the AntlantGIS ontology as OWL file and HTML representation.
+* `/pyscripts` - python scripts for transforming csv tables into RDF.
+
+## Ontology
+
+See the AtlantGIS ontology at http://atlantgis.squirrel.link/ontology/ .
+
+## SPARQL endpoint
+
+AtlantGIS as LOD can be queried via a mainzed SPARQL endpoint:
+
+```
+http://sandbox.mainzed.org/atlantgis/
+```
+
+Send the following query to get all AtlantGIS geometries:
+
+```sql
+PREFIX atlantgis: <http://atlantgis.squirrel.link/ontology#>
+PREFIX geosparql: <http://www.opengis.net/ont/geosparql#>
+PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
+PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
+SELECT ?item ?wkt_geom WHERE {
+  ?item geosparql:hasGeometry ?geom_obj .
+  ?geom_obj geosparql:asWKT ?wkt_geom .
+}
+```
+
+## SPARQLing Unicorn QGIS Plugin
+
+The AtlantGIS triplestore is part of the `SPARQLing Unicorn QGIS Plugin` (>v0.8) which helps to integrate Linked Data and triplestores into QGIS.
