This document discusses open data and its goals of increasing transparency and reducing the gap between citizens and public administrations. It describes barriers to using open data, such as poor data quality, lack of metadata, and empty or incorrect values. The document then introduces datalets and controllets, which are tools for exploring, filtering, grouping, and visualizing open datasets. An edge-centric architecture is proposed to address issues with open data. Future work areas are also discussed.
