  We propose a series of tests that check for the compliance of RDF
triplestores with the GeoSPARQL standard. The purpose of the benchmark is to
test how many of the requirements outlined in the standard a tested system
supports and to push triplestores forward in achieving a full GeoSPARQL
compliance. This topic is of concern because the support of GeoSPARQL varies
greatly between different triplestore implementations, and such support is of
great importance for the domain of geospatial RDF data. Additionally, we
present a comprehensive comparison of triplestores, providing an insight into
their current GeoSPARQL support.
