I don't think this is possible in current API, similar to what happens by default in TextDataset . My use case is biodiversity field observations with GPS positions . I guess an issue would be appropriate. Jean-Marc Vanel

Hi there, Could you provide some more information? Describe the system setup with version numbers. Show the stacktrace. What, if anything, in your setup has changed? Andy On 01/03/2021 07:55, Niket Dixit wrote: Hi Team, We have a apache Jena cluster setup. Since 00:00 am from 1/03/2021,

I tested GeoSPARQL + Lucene API's together, extending previous code for GeoSPARQL alone. Correct results are obtained for both types of queries: GeoSparql & text. Sketch of TDB initialization: textualDataset = TextDatasetFactory.create(dataset, textIndex) load2Cities(textualDatase

Marco, the short answer is yes. please check out the RDF Delta project https://afs.github.io/rdf-delta/ If this does not correspond with your requirements please elaborate on what you want to achieve with the cluster. Best, Marco On Mon, Mar 1, 2021 at 8:03 AM Marco Franke wrote: > Dear all,

Thanks for the explanation. But an implementation is also free to reject a second request, per the specification? So for SPARQL 1.1 a write strategy portable across implementations should be sequential, i.e. one request has to complete before the next one is executed? Is that something SPARQL 1.

[Apache Fuseki Cluster] Is it possible to create a cluster of fuseki

2021-03-01 Thread Marco Franke
Dear all, I read on the JENA e-mail list that an apache Jena cluster setup is possible. Up to know, we use just one Apache Fuseki instance but run in storage and querying limitations. If the possibility is given, we would like to create a cluster of Apache Fuseki instances. Is this possibly tru
