Re: Customizing Turtle pretty printing

I have managed to modify TurtleShell.ShellGraph to output formatted TTL that is very close to rdflib’s longturtle output. The modified functions are: writeRemainingNLinkedLists writeCluster writePredicateObjectList (x2) writePredicateObject writePredicate writeNestedObjectTopLevel

Customizing Turtle pretty printing

I would like to create a custom Turtle pretty printer that does not try to align things like the current pretty printer does. I just want a standard indentation width (e.g. two spaces). So, instead of: ``` [ atime:ProperInterval ; time:hasBeginning[ a

Dynamically loading SPARQL functions from class path

Is it still possible to dynamically load SPARQL functions from the classpath? I have it working with tarql, which uses Jena 3.11, but I can’t seem to get it working with the latest version of Jena: $ JVM_ARGS="-cp

"Safe" flag for riot RDFS inference?

Currently, riot RDFS inference outputs “generalized” RDF which may not be parsable by other tools (including various Jena CLI tools). For example: data.ttl: ``` PREFIX ex: ex:louie ex:birthdate "2022-08-11" . ``` vocab.ttl: ``` PREFIX ex: PREFIX

shiro.ini configuration to disallow PUT to dataset?

I am trying to configure fuseki-server so that * an admin logging in via basic auth can create and update datasets * anonymous users can only query datasets My shiro.ini: [main] ssl.enabled = false plainMatcher = org.apache.shiro.authc.credential.SimpleCredentialsMatcher

Fuseki UI share query links not working?

The Fuseki UI includes a “share query” button that generates a URL with the current query encoded as a parameter. But these URLs aren’t working for me — when I resolve one I just get a blank page with the Apache Jena Fuseki header and nothing else (and no errors in the JS console). Are these

Turtle-star formatted output with annotation syntax?

Jena riot handles parsing Turtle-star annotation syntax, but AFAICT Turtle-star output always uses quoted triples. Are there any plans to support the annotation syntax for output? Thanks, Ryan

Disabling BNode UID generation

Hello, I am trying to experiment with generating diffable N-Triples or flat Turtle files. I was hoping that I could do this by setting JenaParameters.disableBNodeUIDGeneration to true, so that blank nodes would be assigned IDs in increasing order as the parser created them. But it seems that

Using Xerces2 2.12.1 with Jena

I would like to use Xerces2 2.12.1 (with support for XML Schema 1.1) as the Jena XML parser, specifically to gain support for XSD 1.1 datatypes. I see at [1] that “any XML parser can be used with Jena … through the usual mechanism for adding to the application.” But I don’t know what that
