Abstract

<h2>Abstract</h2> Checking the compliance of geospatial triplestores with the GeoSPARQL standard represents a crucial step for many users when selecting the appropriate storage solution. This publication presents the software which comprises the GeoSPARQL compliance benchmark — a benchmark which checks RDF triplestores for compliance with the requirements of the GeoSPARQL standard. Users can execute this benchmark within the HOBBIT benchmarking platform to quantify the extent to which the GeoSPARQL standard is implemented within the triplestore of interest. This enables users to make an informed decision when choosing an RDF storage solution and helps assess the general state of adoption of geospatial technologies on the Semantic Web.

Highlights

The GeoSPARQL standard [1] defines a representation format for geospatial data expressed in RDF [2] as part of the Semantic Web [3], along with a set of geometry functions which work with the same geospatial data
To assess the state of GeoSPARQL compliance in any given triplestore, we developed the GeoSPARQL compliance benchmark, and this paper explains the software behind it
Our GeoSPARQL compliance benchmark has been developed for the HOBBIT platform, which means that the benchmark can be executed via the publicly available platform on various RDF triplestores, which ensures the reproducibility of the results

Summary

Introduction

The GeoSPARQL standard [1] defines a representation format for geospatial data expressed in RDF [2] as part of the Semantic Web [3], along with a set of geometry functions which work with the same geospatial data. Software Impacts 8 (2021) 100071 adopted by RDF triplestores to various degrees which are not necessarily apparent to the user of the individual storage system. A user may want to find out if a triplestore claiming GeoSPARQL support provides support for various coordinate reference systems, or just for the default world geodetic system WGS84; or whether it supports geometries expressed in both WKT [4] and GML [5], or just one of them, etc. To assess the state of GeoSPARQL compliance in any given triplestore, we developed the GeoSPARQL compliance benchmark, and this paper explains the software behind it
