I created a namespace in BlazeGraph 2.1.5 with default configuration, upload this ontology ttl file into it. Then created an adapter in Drupal and get reasoning cache successfully.
However, in a new pathbuilder, when I select a entity in the first step, for example:http://EncodingActs.github.io/annotated/MAon/class:E53-place
It showed errors:
Oops, something went wrong. Check your browser's developer console for more details.
On page /admin/reports/dblog, the error is as below:

So the problematic query is:
PREFIX owl: <http://www.w3.org/2002/07/owl#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
SELECT *
WHERE {
VALUES ?x {<http://EncodingActs.github.io/annotated/MAon/class:E21-Person>}GRAPH ?g { { ?x a owl:ObjectProperty . } UNION { ?x a rdf:Property.}}
}
Searched this answer, I'm sure the Blazegraph namespace in use is triples other than quads. So I guess the problem is that WissKI only use quads mode SPARQL query.
What should I do? No idea :-(
Closed: works as designed
3.0
Code
Switch on Quad-Mode. WissKI needs full SPARQL 1.1 support :)
Cheers!
@Knurg Thank you for your answer. Would you please share me some tools or tutorials to convert my ttl file to quads mode format? I googled nothing useful. I'm still novice to the scope of ontology.
