Hi Erik,
The jena-geosparql code isn't there by default.
Unfortuately, just adding it to the standard build is messy.
All users will see there will be several start-up warnings even if the
GeoSPARQL code isn't being used.
At the moment, add jena-geosparql and also the dependencies it needs.
Setting up maven/gradle is the the robust way to do it because it only
needs jena-geosparql else it needs:
io.github.galbiston:expiring-map
javax.xml.bind:jaxb-api
org.apache.sis.core:sis-referencing
org.slf4j:jul-to-slf4j
org.locationtech.jts:jts-core
org.jdom:jdom2
org.apache.commons:commons-collections4
We hope to have a version of the Fuseki UI for query and data upload,
without the admin controls, which can be added to any Fuseki Main based
server (jena-fuseki-geosparql is Fuseki Main based). That is work to be
done.

Hi,
When embedding geosparql as an assembler in my *fuseki-server *configuration
I get the following error at startup in my docker log:

fuseki-1 | the root file:///fuseki/config-fuseki.ttl#geo_ds has no most

I stripped config-fuseki.ttl to the bare example as follows:

What could be wrong here and what else needs to be done for a proper
*fuseki-geosparql-server* setup?
Regards.
