yaml_ld.flatten.flatten

flatten(
    document: JsonLdInput,
    ctx: JsonLdContext | None = None,
    options: FlattenOptions = DEFAULT_FLATTEN_OPTIONS,
) -> JsonLdRecord

Flatten a ＊-LD document.

Outputs a single array containing all nodes, making no assumptions about their relationships, to simplify data processing and ensure all referenced nodes are included.

Example

flatten.py

import yaml

import yaml_ld

print(yaml.dump(yaml_ld.flatten('pythagorean-theorem.yamlld')))
