Hi Osma, I report it on Jira. Basically, I use the geonames dataset and run the query below.
It takes 4s on Fuseki 2, in the Jena latest version. PREFIX spatial: <http://jena.apache.org/spatial#>PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT distinct ?place{ ?place spatial:intersectBox (32.55668 -117.12865 32.56668 -117.13865) . } On 9 January 2017 at 09:25, Osma Suominen <osma.suomi...@helsinki.fi> wrote: > Hi Samur, > > Can you report this to JIRA with a reproducible full description?
