Edge

class Edge(*, sub: str, pred: str, obj: str, meta: Meta | None = None, standardized: bool = False, subject: Reference | None = None, predicate: Reference | None = None, object: Reference | None = None)[source]

Bases: BaseModel

Represents an edge in an OBO Graph.

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

Attributes Summary

`model_computed_fields`	A dictionary of computed field names and their corresponding ComputedFieldInfo objects.
`model_config`	Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
`model_fields`	Metadata about the fields defined on the model, mapping of field names to [FieldInfo][pydantic.fields.FieldInfo].

Methods Summary

`as_tuple`()	Get the edge as a tuple.
`from_parsed`(s, p, o[, meta])	Construct an edge object from pre-standardized content.
`standardize`()	Standardize the edge.

Metadata about the fields defined on the model, mapping of field names to [FieldInfo][pydantic.fields.FieldInfo].

This replaces Model.__fields__ from Pydantic V1.
