We set out to determine the feasibility of implementing Discrete Global Grid System (DGGS) representations of geometry support in a GeoSPARQL-enabled triplestore, and test the GeoSPARQL compliance for it. The implementation is a variant of Apache Jena's existing GeoSPARQL support. Compliance is tested using an adapted implementation of the GeoSPARQL Compliance Benchmark testing system developed previously to test for GeoSPARQL 1.0 compliance. The benchmark results confirm that a majority of the functions which were set out to be implemented in the course of this paper were implemented correctly and points out possible future work for full compliance.

In 2012 the Open Geospatial Consortium published GeoSPARQL defining ``an RDF/OWL ontology for [spatial] information'', ``SPARQL extension functions'' for performing spatial operations on RDF data and ``RIF rules'' defining entailments to be drawn from graph pattern matching. In the 8+ years since its publication, GeoSPARQL has become the most important spatial Semantic Web standard, as judged by references to it in other Semantic Web standards and its wide use for Semantic Web data. An update to GeoSPARQL was proposed in 2019 to deliver a version 1.1 with a charter to: handle outstanding change requests and source new ones from the user community and to "better present" the standard, that is to better link all the standard's parts and better document \& exemplify elements. Expected updates included new geometry representations, alignments to other ontologies, handling of new spatial referencing systems, and new artifact presentation. This paper describes motivating change requests and actual resultant updates in the candidate version 1.1 of the standard alongside reference implementations and usage examples. We also describe the theory behind particular updates, initial implementations of many parts of the standard, and our expectations for GeoSPARQL 1.1's use.

Expected updates included alignments to other ontologies, handling of new spatial referencing systems, new geometry representations, and new artifact presentation. In this paper, we will discuss the submitted change requests and resulting updates to the standard. We will also discuss the theory behind updates and our expectations for GeoSPARQL 1.1’s use.

http://docs.ogc.org/wp/19-078r1/19-078r1.html The purpose of this document is to outline the benefits of representing geospatial data using semantic and graph technologies. It aims to provide motivation for OGC members to consider the publication of geospatial data using these technologies.
