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.
