Simple utility to download datasets from data respositories.

The goal of this project is to explore machine readable metadata and learn more about writing python packages.

⚠️ script is in early development and needs testing ⚠️

Installation

Supported data respositories with file metadata

• schema.org/Dataset
  • https://dataverse.harvard.edu
  • https://dataverse.no
  • https://snd.se/catalogue
• figshare
  • https://su.figshare.com
  • https://figshare.scilifelab.se

Alternatives

• datahugger - wider repository suport

Improve the script

Adding suport for additional repositories requires test cases and investigation arround how to get file metadata from the landing page.

Please help by testing and reporting issues

Development

• Check out this repository and open a terminal in this directory
• Install dependecies: pip install pyproject.toml
• Run the module without installing it: python3 -m daget

TODO

• Add error handling
• Check empty destination directory
• Improve documentation
• Package script for pip
