Re: Dataset management API

I realised the dataset management API is only available in fuseki-webapp and not fuseki-main. That's unfortunate. On Thu, Jul 13, 2023 at 10:09 PM Martynas Jusevičius wrote: > > Andy, > > Where are the dataset definitions created through the API persisted? > Are they merged wi

Re: Dataset management API

Andy, Where are the dataset definitions created through the API persisted? Are they merged with the datasets defined in the config file, or how does it work? Martynas On Sun, 2 Jul 2023 at 19.03, Andy Seaborne wrote: > > > On 02/07/2023 13:23, Martynas Jusevičius wrote: > > Hi

Executing SHACL over Fuseki dataset

Hi, What is the approach to validating data stored in Fuseki with SHACL? Without having to retrieve a data dump first. I have found some generic projects that claim to translate SHACL to SPARQL: https://github.com/rdfshapes/shacl-sparql https://github.com/Shape-Fragments/SHACL2SPARQL Has anyone

There is one more variable in this picture: Java’s container awareness https://developers.redhat.com/articles/2022/04/19/java-17-whats-new-openjdks-container-awareness Whether it has an impact in this case, I have no idea :) On Thu, 20 Jul 2023 at 11.48, Conal McLaughlin wrote: > Hey Andy, > >

Dataset management API

Hi, Can I see an example of the data that needs to be POSTed to /$/datasets in order to create a new dataset+service? The API is documented here but the data example is missing: https://jena.apache.org/documentation/fuseki2/fuseki-server-protocol.html#adding-a-dataset-and-its-services I hope

Checking that SPARQL Update will not validate SHACL constraints

Hi, I have an objective to only persist constraint-validated data in Fuseki. I have a proxy layer that validates all incoming GSP PUT and POST request graphs in memory and rejects the invalid ones. So far so good. What about SPARQL Update requests though? For simplicity's sake, let's say they

Hi Steve, This looks like Windows shell issue. For some reason /ds is resolved as a filepath where it shouldn’t. Can you try —mem '/ds' with quotes? I’m running Docker on WSL2 and never had this problem. Martynas On Wed, 6 Dec 2023 at 21.05, Steve Vestal wrote: > I am running a VM with

Re: Fuseki growing in size and need for compaction

Andy, Not directly related, but would different storage backend address issues like this? It might sound a bit like the legacy SDB, but AFAIK oxigraph, Stardog and another commercial triplestore use RocksDB for storage. https://github.com/oxigraph/oxigraph

Fuseki: multiple instances vs. multiple datasets
