An interface that provides relation graph abstractions.

Note

this interface is now largely subsumed into the BasicOntologyInterface

entailed_outgoing_relationships(curie: str, predicates: List[str] | None = None) → Iterable[Tuple[str, str]][source]

The return relationship map is keyed by relationship type, where the values are the ‘parents’ or fillers

OWL formulation:

  • is_a: {P : SubClassOf(C P), class(P)}

  • R: {P : SubClassOf(C ObjectSomeValuesFrom( RP), class(P), property(P)}

Parameters:

  • curie – the ‘child’ term

  • predicates –

Returns:

entailed_incoming_relationships(curie: str, predicates: List[str] | None = None) → Iterable[Tuple[str, str]][source]

The return relationship map is keyed by relationship type, where the values are the ‘parents’ or fillers

OWL formulation:

  • is_a: {P : SubClassOf(C P), class(P)}

  • R: {P : SubClassOf(C ObjectSomeValuesFrom( RP), class(P), property(P)}

Parameters:

  • curie – the ‘child’ term

  • predicates –

Returns:

entailed_relationships_between(subject: str, object: str) → Iterable[str][source]

Yield the predicates of all valid relationships connecting subject and object, both direct and indirect

Parameters:

  • subject –

  • object –

Returns:

autosave: bool

For adapters that wrap a transactional source (e.g sqlite), this controls whether results should be auto-committed after each operation

exclude_owl_top_and_bottom: bool

Do not include owl:Thing or owl:Nothing
