Re: Problems when querying the SPARQL with Jena

Shouldn't also 1.8 1.8 be a minimum of 17 given the Jena version 5.0.0-rc1? Best regards, Øyvind On Tue, Mar 12, 2024, 14:54 Andy Seaborne wrote: > > > On 12/03/2024 13:02, Anna P wrote: > > Hi Lorenz, > > Thank you for your reply. Yes, I used maven to build the project. Here > are > >

Re: Jena hangs on deleted files

2023-09-07 Thread Øyvind Gjesdal
What does the content of the tdb2 folder look like? I think compact by default never deletes the old data, but you have parameters for making it delete the old content on completion. `--deleteOld` can be supplied to the tdb2.tdbcompact command line tool and `?deleteOld=true` can be supplied to

Hi Adrian, >From the git history I can see that we were using Elasticsearch 6.4.3 and Fuseki 3.10.0 when we experimented with it and had it running. AFAIK Both Lucene and Elasticsearch indexes the data for you as the triplestore updates, without having to do anything, using a normal

Hi Adrian, We tried the elastic-search module when it was available and had your use-case in mind with facets. But as far as I remember I don't think it was possible to use aggregations (at least from the sparql side of things). I understood the elasticsearch-module as an alternative to the

Re: Executing SHACL over Fuseki dataset

2023-06-06 Thread Øyvind Gjesdal
I haven't tried it, but it looks like it is implemented, and you can configure a SHACL service on datasets, in the assembler for Fuseki. https://jena.apache.org/documentation/shacl/#integration-with-apache-jena-fuseki You can then use the api and post shapes as files for validating datasets:

Re: Lucene Faceted search

2023-02-14 Thread Øyvind Gjesdal
Hi, This is also something I've thought about, since we have a dated elasticsearch integration for creating facets from endpoints, and we use aggregated sparql queries for counting which sometimes becomes slow-ish, and has to be turned off for larger datasets. An idea I had around 3 in how it

Re: Jena Full Text Search poor performance

2022-06-15 Thread Øyvind Gjesdal
Hi Pawel, I think this could be due to the text:query being evaluated late in the query, and other statements first computing many results, before the text query limits it down. Maybe the contains filter gets applied earlier? Would reordering the statements, expanding the property path and/or

TDB2 persistence and jena fuseki upgrades

2022-05-09 Thread Øyvind Gjesdal
I've recently completed some upgrades using the fuseki binaries, first with major versions, from different 3.X to 4.4 and then again from 4.4 to 4.5. * I noticed that on the upgrades my tdb2 databases returned no results in sparql after upgrading, but they both had similar file size in the

I have a working setup (on fuseki 3.14) where I can see different results using AND/OR, and where "~" fuzzy operator also works. Differences from your config seem to be that I haven't configured much for the index, only the directory and entity map. Would testing if a minimal config works and

Re: Building a spatial index with jena/fuseki

2018-09-17 Thread Øyvind Gjesdal
Looking at our very similar config (based on the fuseki examples) only difference I see (except from the additional library) is that our config uses TDB, and your config uses TDB2. I believe tdbloader2 generates tdb1 data ( I could be wrong), since I remember using it pre tdb2 release, so there
