DOI Resolver Updater for DataCite

This Python script updates the target URLs of DOIs registered via DataCite.

It reads a CSV file containing DOIs and their corrected URLs, and sends updates to the DataCite API.

---

✅ Features

• Reads DOIs and new URLs from a CSV file
• Sends PUT requests to the DataCite REST API to update the url field
• Includes:
  • Logging to a file
  • Progress bar via tqdm
  • Dry run mode (to preview changes without sending updates)

---

📄 CSV Format

The input file should contain the following headers:

doi;url
10.xxxx/abcde;https://correct.link/abcde
10.xxxx/fghij;https://correct.link/fghij

Note: Use ; as the separator (common in Excel exports).
