Apr 1, 2025April 2025 monthly summary for spraakbanken/metadata. Key feature delivered: Switch Corpus Statistics Downloads to ZIP Format. Updated URLs to point to ZIP-compressed statistics files across corpus definitions and YAML configurations, enabling downloads of compressed formats. Major bug fixed: Fix Metadata Creation Dates in YAML. Corrected incorrect 'created' dates in three YAML files (flashback-dator.yaml, flashback-flashback.yaml, flashback-resor.yaml) from future 2025 dates to historical 2014 dates. Overall impact: Improved data delivery efficiency, reliability, and data provenance; reduced risk of downstream issues in automated pipelines. Technologies/skills demonstrated: YAML configuration management, URL/file format handling, Git-based version control, and data governance practices. Business value: reduced bandwidth usage, faster access to statistics, and improved metadata accuracy.
