European Union Countries Indicators Dataset v1.0.1

European Union Countries: A Curated Dataset on EU Members for Education and Data Science

Release Notes: Version 1.0.1

Digital Object Identifier (DOI) Synchronization The repository has been updated to reflect the official permanent DOI: 10.5281/zenodo.19659891

This replaces the initial reservation ID, ensuring all persistent links and badges resolve correctly to the published dataset.

• Metadata Consistency Alignment Synchronized the versioning across all control files—.zenodo.json, CITATION.cff, and version.txt—to v1.0.1. This ensures that automated indexing tools and repository crawlers recognize the correct asset state.

• Citation Schema Optimization Updated the CITATION.cff file with the definitive DOI and version number. This allows researchers and students to generate accurate academic citations automatically via GitHub and Zenodo integration.

• Documentation and Badge Correction The README.md has been revised to include the verified Zenodo DOI badge. This provides immediate visual confirmation of the dataset's peer-reviewed status and availability in the open-access ecosystem.

• Resource Classification Validation Verified the manual override of metadata to ensure the resource is strictly classified as a Dataset (and not software), preserving the integrity of the pedagogical methodology and its academic indexing.

• Integrity of Core Datasets: The primary data files (CSV and Excel formats) remain unchanged and unmodified.
