Hi all,
slightly off-topic, but given the ongoing ESWC 2023 conference, I want
to share two papers that might be interesting for the one or the other:

Hi all and late happy new year!
Nice work with the modules Andy.

Hi,
That is the same issue I also reported very very hidden in a Github PR:

might be missing, maybe close to or in developers doc, but I don't know

Hi,
just want to inform about a minor limitation in the current build process:
Building Jena from Maven fails when you have something already running
on port 3030 (e.g. a Fuseki on standard port) because there is now some

Hi Andy,
yes I also did with rewriting which indeed performed faster. Indeed
the issue here was that TDB2 didn't use the stats.opt file because it
was in the wrong location. I'm still not convinced that it

I'm also trying to set it up locally on the same server as the TDB2

rent servers with way more disk space ... "lesson learned"

Try running the queries twice in the same server.
TDB does no pre-work whatsoever so file system caching is significant.

Hi all,
just as a follow up I loaded Wikidata latest full into TDB2 via xloader
on a different less powerful server:

Hi all,
Fuseki UI module build fails when doing

need something specific?

In addition to the current discussion, I'd bring up another potential
improvement: query tabs
If I'm not totally blind, this isn't possible in the current UI? At
least in my work I'm quite often working with multiple queries and so
far I've to open multiple windows in Fuseki which makes me usi
oks like yasgui doesn't support RDF-star.
I wonder how difficult it is to add the feature.
jena-fuseki-ui:package.json
@triply/yasr => ^4.21.1
which is latest.

Hi all,
just using latest Fuseki UI and it looks like
1) RDF Star isn't supported by the query parser - it complains with some
red marker but at least we can run queries nevertheless
2) more problematic, it can't visualize RDF Star neither from SELECT
queries in a table nor for CONSTRUCT que
Hi,
not sure if intended or simply just forgotten after adding the GeoSPARQL
assembler support (finally, thanks for that Andy!), but currently it
looks like the Fuseki webapp module is missing the geosparql module
import which leads to a Fuseki distribution without GeoSPARQL support by
defaul
Nice progress so far.
Just a probably dumb question: how do I start Fuseki with UI now when
enabling GeoSPARQL via assembler? I tried to use the fulljar package
java -jar target/jena-fuseki-fulljar-4.4.0-SNAPSHOT.jar --desc
~/fuseki-geosparql.ttl /ds
but this seems to lack the webapp contex

I'm a bit surprised that this time it was 8h faster than last time, 31h
vs 39h. Not sure if a) there was something else on the ser
easier.
I'm also watching the CPU temperature. When the graphics aren't
active, the fans aren't even on. After a few minutes of active screen
the fans spin up but the temperatures are still well within the
limits. The machine is raised up by 1cm to give good airflow. And I

what is a "sub-resource" in RDF? Are you talking about CBDs? Like what
