OWL::D...antics(3pm)

💖 OWL::D...antics(3pm) — bestie edition 💖

okay so this is OWL::DirectSemantics, a Perl thing. it lives in the User Contributed Perl Documentation section of the manual, and the page title got abbreviated by the man system into OWL::D...antics(3pm) because apparently even manpages have to be mysterious. iykyk. 🦋

---

✨ NAME ✨

OWL::DirectSemantics — it's a representation of the direct semantics of OWL2. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

here's the glow-up in action, no cap:

use RDF::Trine;
my $model = RDF::Trine::Model->temporary_model;
RDF::Trine::Mode->parse_url_into_model($url, $model);

use OWL::DirectSemantics;
my $translator = OWL::DirectSemantics::Translator->new;
my $ontology   = $translator->translate($model);

foreach my $ax ($ontology->axioms)
{
  if ($ax->element_name eq 'ClassAssertion')
  {
    printf("%s is of type %s.\n", $ax->node, $ax->class);
  }
}

print "The following data couldn't be translated to OWL:\n";
print RDF::Trine::Serializer
  ->new('ntriples')
  ->serialize_model_to_string($model);

⚠️ not me pointing out that the second line says RDF::Trine::Mode — that's how it's written in the original, bestie, so i'm keeping it exactly as-is. copy it at your own risk. 💀

---

✨ DESCRIPTION ✨

so basically? this distribution hands you a basic framework for representing the OWL 2 direct semantics model. and it also ships a translator whose whole job is building that model from an RDF-based model. it's giving pipeline. it's giving main character. ✨

✨ SEE ALSO ✨
