Re: Support for non-string plain literals?

Hi Jean-Marc, I'm aware of createTypedLiteral, but I don't want to generate typed literal, but a plain one instead, as I have indicated in my question. For example, 1000 instead of "1000"^^xsd:integer. - Jindřich -- Jindřich Mynarz http://mynarz.net/#jindrich On Sat, Jun 25, 2016 a

Create Dataset with unionDefaultGraph on

Hi, is it possible to create a Dataset (via org.apache.jena.query.DatasetFactory) so that the default graph is the union of all named graphs, similarly to using tdb:unionDefaultGraph in TDB? Thanks, Jindřich -- Jindřich Mynarz http://mynarz.net/#jindrich

Unequal SPARQL algebras

RDFS inference produces invalid data

Hi, it is reasonably common in RDF vocabularies to see that a property is defined as an rdfs:subPropertyOf a blank node, such as in this example: ### vocabulary.ttl PREFIX : PREFIX owl: PREFIX rdfs:

Reading UUID URNs from InputStreams in Jena 4

Hi, when reading data with UUID URNs from InputStreams in Jena 4 I get the error "Bad IRI: Not a valid UUID string". For example, when I run the following: Model model = ModelFactory.createDefaultModel(); String data = " < http://ex.org/a> ."; try (ByteArrayInputStream in = new
