PR Summary

• Improved Data Identifier Matching
  An upgrade was carried out on the data identifier matching function ('foundry.py'). Before, it only returned the first match it found, now it will run through every result until it finds a perfect match. Additional warning logs have also been incorporated should the function fail to find an exact match.

• Introducing a new Minimal Data Framework (MDF) Client
  We have introduced a new component, mdf_client.py, which will replace the dependency on the previous mdf_forge while also bringing in more features.

  Key Features Include:

  • StagingUploader Class: Manages file uploads to the MDF Staging endpoint eliminating the need for Globus Connect Personal.
  • File and Directory Management: New methods to create and handle staging directories and file uploads.
  • MDFClient Class: Allows for dataset search and download while including advanced filters for resource types, organizations, and DOIs.
  • Improved Search and Download Features: Implementation of a search method for finding datasets based on parameters, and added download functionality via Globus Transfer.
