Re: Ontology rdfs:range owl:Thing

I think you are misunderstanding the meaning of rdfs:range (a very common mistake) Per definition, rdfs:range is an instance of rdf:Property that is used to state that the values of a property are instances of one or more classes. So, rdfs:range is n

Re: Writing Jena Model to CSV

CSV is not a valid RDF serialization format as mentioned (only as a format for SPARQL results). If you want something similar to CSV for serializing an RDF Model, try using N-triples. On Thu, Sep 8, 2016 at 10:22 AM, Martynas Jusevičius wrote: > I think CSV is for writing ResultSet (SELECT resu

Re: Question about RDF collections

Just remember that there is no ordering in this. [Document_A] --contains--> [Paragraph_1] [Document_A] --contains--> [Paragraph_2] [Document_B] --contains--> [Paragraph_2] is equivalent to [Document_A] --contains--> [Paragraph_2] [Document_B] --contains--> [Paragraph_2] [Document_A] --contains--

Property Paths programmatically

I have written code that looks like this: Property myPropertyA = ... Property myPropertyB = ... Property myPropertyC = ... Model model = ... NodeIterator iterA, iterB, iterC; RDFNode nodeA, nodeB, nodeC; if ( (iterA = model.listObjectsOfProperty(myPropertyA)).hasNext()

Using Jena inside GWT client-side

Let me start by saying it's been a really long time since I have done any front-end programming. In the context of an RDF based restful API I've been involved in developing, it was always on my mind to create a GUI of sorts. I was thinking of going with JavaFX at some point, but never got around

Fuseki2 Embedded Server for Jena 3.0.1

Hi everybody, I am trying to run Fuseki2 embedded. I have found the artifact org.apache.jena jena-fuseki-embedded 2.4.1 However, this artifact appears to depend on Jena 3.1.1. I have another external library that depends on Jena 3.0.1 Is there a Fuseki2 embe

Re: Experience with large number (e.g. 1M) of Named Graphs in Fuseki?

My first guess would be no, it wouldn't hurt performance. Although I have limited experience on Fuseki (just using it as a second test endpoint to verify SPARQL compatibility), I am using a similar approach on a different RDF store (currently at about 650,000 graphs on one deployment) I would imagi

Overloading SPARQL operators for User defined non-XSD data types

In reference to the Rational datatype example in 'User defined non-XSD data types' at the bottom of the page at ' https://jena.apache.org/documentation/notes/typed-literals.html' Is it possible, and if so how to do it, to define/override suitable methods (which methods?) in the class definition s

Jena 3 - Printing ^^xsd:string in output

From: https://jena.apache.org/documentation/migrate_jena2_jena3.html#rdf11-plain-literals "Output is in the datatype-less form (an abbreviated syntax) even in N-triples." - Is there a way to change the default behavior and print the ^^xsd:string part. Mostly interested when serializing to turtle
