Meta

python-re3data is a Python library that simplifies interacting with the re3data (Registry of Research Data Repositories) REST API, allowing you to easily retrieve and process metadata about research data repositories in a convenient and Pythonic way.

>>> import re3data
>>> response = re3data.repositories.list()
>>> response
[RepositorySummary(id='r3d100010468', doi='https://doi.org/10.17616/R3QP53', name='Zenodo', link=Link(href='https://www.re3data.org/api/beta/repository/r3d100010468', rel='self'))]
... (remaining repositories truncated)

>>> response = re3data.repositories.get("r3d100010468")
>>> response
Repository(re3data_org_identifier='r3d100010468', repository_name=RepositoryName(value='Zenodo', language=<Languages.ENG: 'eng'>), additional_name=[], repository_url='https://zenodo.org/', repository_identifier=['FAIRsharing_doi:10.25504/FAIRsharing.wy4egf', 'RRID:SCR_004129', 'RRID:nlx_158614'])

Features

• Pythonic API interactions: Interact with the re3data API in a Pythonic way, without having to worry about low-level HTTP requests or XML parsing.
• Repository metadata retrieval: Easily fetch and process metadata about research data repositories using re3data.repositories.list().
• Repository details retrieval: Get detailed information about a specific repository using re3data.repositories.get(repository_id).
• XML response parsers: API XML responses are parsed into Python dataclasses, providing convenient access to the elements of the re3data.org Schema 2.2 XML Schema. This makes it easy to work with the rich metadata provided by the API.
• Flexible response options: The response type can be switched between:
  • dataclass (default): Returns a Python dataclass object, allowing convenient access to the element of the re3data schema
  • response: Returns a Python object representing the API response
  • original XML (str): Returns the raw XML response from the API
  • JSON (str): Returns a JSON representation of the API response
  • dictionary: Returns a dictionary representation of the API response
  • csv (str): Returns a CSV representation of the API response
  • dataframe: Returns a pandas.DataFrame representation of the API response

Requirements

Python >= 3.10

python-re3data is built with:

• HTTP Requests: httpx, a modern and efficient HTTP client library, handles all API interactions.
• XML Parsing: xsdata, a powerful tool for generating Python dataclasses from XML schemas, simplifies processing of API responses.
• Optional CLI: typer, a popular library for building command-line interfaces, powers the user-friendly interface.
• Optional DataFrame/CSV: pandas, a powerful and flexible data analysis library, enables generation of DataFrames and CSV files from parsed XML responses.

Installation

You can install python-re3data via pip from PyPI:

python -m pip install python-re3data

or pull the Docker image from GHCR:

docker pull ghcr.io/afuetterer/python-re3data:latest
