Conference Paper

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 GeoSPARQ...

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 impor...

In 2012 the Open Geospatial Consortium published GeoSPARQL defining “SPARQL extension functions”, “RIF rules” and “an RDF/OWL ontology for [spatial] information”. 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 us...
Technical Report
Full-text available
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.

... The properties of the spatial ontology mainly define the topological spatial relations between geographic objects, as well as the geometry literal [26], which is the serialization standard used when generating geometry descriptions and the supported geometry types. In addition, the properties of the spatial ontology also include Metric [26], which are scalar spatial properties that describe the geographic object. ...
... Due to the anchoring of references in predefined tables, relational modelling does not have the flexibility and openness required to create a Digital Twin. In contrast, with the help of an ontology, semantic modelling has advantages through graph technologies, such as flexibility and freedom for modelling, openness and transparency for reproducibility, and standardisation through ontologies and (geo-)vocabularies [118]. Semantics allows possible flexibility in the connection of archaeological and geometrical content and the possible application of a (changeable) set of rules that connects geometry and archaeology and provides the basis for conclusions. ...
