Question to the construction of OWL Literals #1070

Closed psiotwo closed 2 years ago

psiotwo commented 2 years ago

I have came across this question when investigating https://github.com/ontodev/robot/issues/1020.

When the plain literal "a@b" is processed using getOWLLiteral method, it tries to interpret it as a lang literal. What is rationale behind this behaviour? In the ticket above, it is causing problems when at-signs are used inside a literal.

That's the syntax for rdf:langString literals. If the literal must be interpreted as xsd:string, it should be typed explicitly. Unfortunately the syntax choices for literals are confusing to say the least, they've confused me enough times and I'm not the only one bitten by them.

@ignazio1977 thanks for pointing me to the spec - I missed that bit. Although I can understand the intention, it is more than confusing, indeed ...
