Turtle syntax is not fully supported

[tarcisiotmf]

When loading the ontology at http://purl.org/emi into Qlever, the following error occurs:

2024-07-26 14:30:18.295 - ERROR: Parse error at byte position 15878: Prefix [ rdf was not previously defined using a PREFIX or @prefix declaration The next 500 bytes are: owl:Class ; owl:unionOf ( emi:ChemicalStructure emi:ChemicalTaxonAnnotation ) ] ;
However, the problem is not the prefix but the fact that '[' turtle syntax for blank nodes is not supported, in my opinion. After using the .nt version of this ontology I was able to index/load it with qlever.

P.s.: thank you for sharing this really impressive RDF store you have been building.

Hi,
Thanks for reproting this.
I am just loking into this bug. Can you confirm that this fails, when you specify the setting ascii-prefixes-only:true and works when you set this to false?

@joka921 Thanks for your quick reply! Probably you were already able to replicate the issue but in any case you can find below the config used where "ascii-prefixes-only" = true:

SETTINGS_JSON   = { "languages-internal": [], "prefixes-external": [""], "locale": { "language": "en", "country": "US", "ignore-punctuation": true }, "parallel-parsing" : true, "ascii-prefixes-only": true, "num-triples-per-batch": 1000000 }
