Description

Add Europeana API integration for metrics collection

This PR adds a new script europeana_fetch.py that fetches and aggregates data from the Europeana Search API.
The script collects high-level statistics about cultural heritage content available through Europeana, focusing on data provider distribution and content types rather than fragile license parsing.

Technical details

Script Location: scripts/1-fetch/europeana_fetch.py

• Data Output: data/2025Q4/1-fetch/europeana_1_count.csv
• Key Features:
  • Fetches data from Europeana Search API using multiple content queries
  • Aggregates by DATA_PROVIDER and content metadata
  • Includes proper error handling and API rate limiting
  • Integrates with existing project structure and git workflows
• Environment: Updated env.example with EUROPEANA_API_KEY placeholder

Tests

1. Set up Europeana API key in environment variables
2. Run the script: python scripts/1-fetch/europeana_fetch.py --enable-save
3. Verify CSV output is generated in data/2025Q4/1-fetch/europeana_1_count.csv
4. Check that data contains aggregated counts by DATA_PROVIDER

2. you review the pull request Files changed tab yourself to see if there are any unintended files or other obvious issues

Hello....I reviewed the Files changed tab in my pull request as you advised.
Only the intended updates to europeana_fetch.py are listed.
The other files in the folder (env.example and sources.md) came from merging the latest main branch into my feature branch and they do not show up in the diff .
