Convert to pd.DataFrame.

By default, shows all direct fields, except updated_at.

Use arguments include or feature to include other data.

Parameters:

  • include (str | list[str] | None, default: None) – Related fields to include as columns. Takes strings of form "ulabels__name", "cell_types__name", etc. or a list of such strings.

Examples

Include the name of the creator in the DataFrame:

>>> ln.ULabel.df(include="created_by__name"])

Include display of features for Artifact:

>>> df = ln.Artifact.df(features=True)

classmethod inspect(values, field=None, *, mute=False, organism=None, source=None, strict_source=False)

Inspect if values are mappable to a field.

Being mappable means that an exact match exists.

Parameters:

  • values (list[str] | Series | array) – Values that will be checked against the field.

  • field (str | DeferredAttribute | None, default: None) – The field of values. Examples are 'ontology_id' to map against the source ID or 'name' to map against the ontologies field names.

  • mute (bool, default: False) – Whether to mute logging.

  • organism (str | Record | None, default: None) – An Organism name or record.

  • source (Record | None, default: None) – A bionty.Source record that specifies the version to inspect against.

  • strict_source (bool, default: False) – Determines the validation behavior against records in the registry. - If False, validation will include all records in the registry, ignoring the specified source. - If True, validation will only include records in the registry that are linked to the specified source. Note: this parameter won’t affect validation against bionty/public sources.

Return type:
