Extend rdflib's TurtleSerializer and add a custom ordering of subjects

Deepak Unni requested to merge add-ordered-output into main

The exported output will contain triples with the following fixed ordering:

  • Ontology metadata (i.e. resource that is of type owl:Ontology)
  • Classes (i.e. classes that are of type owl:Class)
  • Deprecated Classes (i.e. classes that have an annotation property of owl:deprecated)
  • Annotation Properties (i.e. resources that are of type owl:AnnotationProperty)
  • Object Properties (i.e. resources that are of type owl:ObjectProperty)
  • Datatype Properties (i.e. resources that are of type owl:DatatypeProperty and rdfs:Datatype)
  • Named Individuals (i.e. resources that are of type owl:NamedIndividual)
  • Root nodes from terminologies (i.e. classes that are rdfs:subClassOf sphn:Terminology, and its subclasses)
  • Other (all remaining resources)

TODO:

  • Order restrictions
  • Order values in owl:someValuesFrom restriction
