🚍🏙️ Spatial analytics in QLever is crazy good! Here’s a query from the OpenStreetMap dataset showing all Jakarta buildings within 400m of a public transport stop. You can play with the examples on their endpoint:

I had to check if this was for real, but he actually posted it and even defends it, saying anyone who disagrees just doesn’t get it.
QLever codebase is ~ 130k lines of C++, after 10 years (minus tests). Just to give you an idea of how stupid this statement is.

How close is every building 🏠 in Switzerland to the nearest public transport stop? 🚆
With QLever and some clean RDF data, this is easy.

Proud to announce our second venture! We teamed up with Hannah Bast and Johannes Kalmbach, the makers of the incredibly fast and scalable RDF triplestore QLever, to provide commercial support and services under @qleverize.com.
If you have hard problems where graphs could help, let’s talk.
If you have hard problems where graphs could help, let’s talk.
We scale where others fail. QLever makes knowledge graphs with hundreds of billions of triples possible on commodity hardware, unlocking RDF’s full potential at unprecedented scale.
QLeverize is here to support that transformation. Read our press release:

You might’ve noticed that QLever has been stuck without updates of OHM data for a few weeks. The QLever team has resumed daily updates and also upgraded the endpoint to the latest version of the software. The upgrade comes with breaking changes that might affect any queries you might have stashed away, due to the elimination of the osm2rdfmember: prefix: Old predicate New predicate Description osmrel:member osmrel:member A member within the relation osmrel:member/osm2rdfmember:id osm...
