Hello everyone,

now that you released the first version with support for GeoSPARQL, you
might also be interested in

- running Jena on a new benchmark system called Geographica 2 [1]
- as well as check for feature support compared to other systems (Table
1 in the paper [2])

Might be a good idea to mention on the Jena website which of those
features are also possible with Jena? And maybe even planned for future
work?

Regarding running the benchmark, I don't know how much time and effort
it takes to setup and run the benchmark.

Moreover, it might also worth to let the authors know that there is
another system now with GeoSPARQL support given that I assume they might
re-run their benchmark in the future and update their benchmark results page

By the way, looking at the benchmark results, except for Strabon system,
the Spatial join performance looks horrible.

I know all of those things are time costly, but nevertheless I wanted to
let you know of this system/paper which I spotted quite recently. Some
of you might indeed already be aware of it.


Cheers,

Lorenz
