Docling Core

Docling Core is a library that defines the data types in Docling, leveraging pydantic models.
Installation
To use Docling Core, simply install docling-core from your package manager, e.g. pip:
pip install docling-core

Development setup
To develop for Docling Core, you need Python 3.9 / 3.10 / 3.11 / 3.12 and Poetry. You can then install from your local clone's root dir:
poetry install

To run the pytest suite, execute:
poetry run pytest test

Basic Usage

You can validate your JSON objects using the pydantic class definition.
from docling_core.types import Document

data_dict = {...} # here the object you want to validate, as a dictionary
Document.model_validate(data_dict)

data_str = {...} # here the object as a JSON string
Document.model_validate_json(data_str)

You can generate the JSON schema of a model with the script ds_generate_jsonschema.
# for the `Document` type
ds_generate_jsonschema Document

# for the use `Record` type
ds_generate_jsonschema Record

Documentation
Docling supports 3 main data types:

Document for publications like books, articles, reports, or patents. When Docling converts an unstructured PDF document, the generated JSON follows this schema.
The Document type also models the metadata that may be attached to the converted document.
Check Document for the full JSON schema.
Record for structured database records, centered on an entity or subject that is provided with a list of attributes.
Related to records, the statements can represent annotations on text by Natural Language Processing (NLP) tools.
Check Record for the full JSON schema.
Generic for any data representation, ensuring minimal configuration and maximum flexibility.
Check Generic for the full JSON schema.

The data schemas are defined using pydantic models, which provide built-in processes to support the creation of data that adhere to those models.
