Node

class Node(*, id: str, lbl: str | None = None, meta: Meta | None = None, type: Literal['CLASS', 'PROPERTY', 'INDIVIDUAL'], reference: Reference | None = None, standardized: bool = False)[source]

Bases: BaseModel, StandardizeMixin

Represents a node 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

`alternative_ids`	Get the alernative identifiers for this node.
`created_by`	Get the creator of the node.
`creation_date`	Get the creation date of the node.
`curie`	Get the CURIE string representing this node or error if not normalized.
`definition`	Get the definition of the node.
`definition_provenance`	Get the provenance CURIEs for the definition.
`deprecated`	Get if the node is deprecated.
`identifier`	Get the identifier for the node if it has been standardized.
`model_config`	Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
`namespace`	Get the OBO namespace.
`prefix`	Get the prefix for the node if it has been standardized.
`properties`	Get the properties for this node.
`replaced_by`	Get the identifier that this node was replaced by.
`synonyms`	Get the synonyms for the node.
`xrefs`	Get the xrefs for the node.

Methods Summary

`get_provenance`()	Get provenance CURIEs from definition and xrefs.
`parse_curie`()	Parse the identifier into a pair, assuming it's a CURIE.
`standardize`()	Ground the node to a standard prefix and luid based on its id (URI).
