Converting BNode to Resource

Dear all, I am curious whether there is exist a method in Jena that can conveniently “convert” a blank node to a resource. e.g., suppose that I have a model M1 that contains a blank node _:a which has several properties (e.g., rdfs:label, etc), I would like to execute something like: M1.conve

Jena TDB / Fuseki as an OSGi Bundle

Hi, I am currently working on implementing RDF storage as part of an OSGi application. In our settings, there will be around tens of update and hundreds of queries everyday. At the moment, the RDF data is stored as a file that loaded and unloaded everytime there is an update / query. Howev

Manage Repository (add update delete) in Fuseki from Java

Hi, Is it possible to manage (e.g., add or delete) repositories in Fuseki2 (Stand Alone) from Java code? I tried to browse through the documentation [1], but can’t find any clue on how to do that. Thanks in advance! Fajar [1] https://jena.apache.org/documentation/fuseki2/

Re: Getting all classes and properties from DAML-based ontology

Hi Arif, AFAIK, DAML format is not supported by Jena at the moment (also mentioned by Dave before). It was used around year 2000 I think, and then replaced by RDF(S)/OWL format as a standard. I check the GEDCOM ontology, and it shouldn’t be too hard to recreate them in OWL format from scratch

Fuseki2 Client Access from Java

Hi, Are there any documentation on how to access Fuseki2 server from a Java client (to manage datasets)? the current link [1] is empty and if there are any pointer to certain classes to start with, I am happy to explore. Thanks in advance! Fajar [1] https://jena.apache.org/documentation/fuse

Configuring TDB to use inference within assembler file

Hi, I am trying to run TDB with jena rules inference using assembly file. I could do it with Fuseki, but I cannot find any example to run it with non-Fuseki TDB storage. Is it possible to do this? I copy my assembler file below. Using this assembler, it seems that Jena only read from the dat

Apache Jena OSGI release?

Hi All, Currently, I found that Apache Clerezza [1] is bundling the Jena for OSGi environment, but as far as I tried it, currently there are no support for Jena-TDB in it (Maybe I do it wrong though..) So I have two questions: 1. Is there any plan to release the official Apache Jena (ARQ, co

TDB Initialisation size

Hi All, I tried the following code to create empty Jena TDB repo: Dataset ds = TDBFactory.createDataset("examples/tdb-1"); And surprisingly I got the massive 201,3 MB empty repo on my “examples/tdb-1” folder on my Mac. Is this a normal size for an empty TDB repo? if yes, is there any docume
