Geographica 2 Benchmark

Evaluating Geospatial RDF stores Using the Benchmark Geographica 2

Geographica 2 improves the Geographica benchmark by adding one more workload, extending the existing workloads and evaluating 5 more RDF stores. Using three different real world workloads, Geographica 2 tests the efficiency of primitive spatial functions in RDF stores and their performance in real use case scenarios, a more detailed evaluation is performed using a synthetic workload and the scalability of the RDF stores is stressed with the scalability workload. In total eight systems are evaluated out of which six adequately support GeoSPARQL and two offer limited spatial support.

Documentation for the project is maintained at our Geographica 2 web site.

geographica2's Issues

server down - workaround not working

Hi, i read your notice:

Caution (upd 11/Jan/2024): The servers hosting Maven repositories (including Geographica2) with the Mercurial VSC are unfortunately under maintenance since Dec/2023. The servers will be up as soon as possible and the normal build process should work as expected.
For now, the user can use our team's Github repository as explained below.

However, some assets fail to download as also http://dev.opensahara.com/ seems down (see build output below).

Any thoughts or workarounds?

Best Valentijn
