Main Characteristic

Do you want to get the most of your relational data combining them with linked geospatial data without converting them to RDF? No problem. Ontop-spatial can create virtual geospatial RDF graphs on top of your geospatial databases (Currently PostGIS, SpatiaLite and Oracle spatial are supported). Your geometries will be mapped to GeoSPARQL geometry literals using ontologies and R2RML/OBDA mappings.

Detailed Description

Execution environment: linux

Version of the environment: Linux

Additional information: Ontop-spatial supports the following GeoSPARQL components: core, Topology vocabulary, Geometry topology extension, RDFS entailment extension, Query rewrite extension and subset of the Geometry Extension. Deciding to create virtual geospatial RDF graphs instead of materializing them does not necessarily mean that efficiency needs to be sacrificed. In fact, experimental evaluation has shown that in most cases, Ontop-spatial achieves better response times than traditional geospatial RDF stores

The project is a Maven project. Compiling, running the unit tests, building the release binaries all can be done using maven. To make it more practical we created several .sh scripts that you can run on any unix environment that has maven installed. The scripts are located in the folder 'scripts', look at that folder for more information.

GDPR Requirements
Ontop-spatial allows the users to create virtual geospatial RDF views on top of their geospatial databases and pose GeoSPARQL queries without converting their data. The software itself is GDPR compliant. Documents are processed locally and all data remains on the user's local computer. However, the users must ensure that they have the authority to store and process the documents, for example if they contain personal data or other sensitive GDPR-relevant information.
