+**Data Info:**
+
+OpenCouncil is a structured dataset of Greek municipal council proceedings, containing meeting transcripts, agendas, decisions, speakers, discussion topics, voting outcomes, and associated metadata from local government bodies across Greece. 
+The dataset is generated from publicly available council meetings using automated transcription, speaker identification, topic segmentation, and human verification workflows. 
+It enables full-text search, analysis of public deliberations, civic transparency research, political science studies, natural language processing, and the development of tools that improve access to local government decision-making. 
+The data includes meeting-level, topic-level, and speaker-level information, linking discussions to official decisions and administrative records where available (https://opencouncil.gr/en).
