Recognising the increasing availability of open data and the interest for their exploitation, the OpenDataMonitor (ODM) project has designed and developed a platform (http://opendatamonitor.eu) that will enable interested stakeholders to gain an overview of this evolving open data “landscape”. To that end, the research and development activities undertaken throughout the ODM project, focus on the main directions outlined below:
• facilitating and automating the collection of metadata from open data catalogues via an extensible and customizable harvesting framework;
• cleaning and integrating the raw collected metadata, overcoming the high heterogeneity of schemas, values and formats found in the various open data sources, via an integration and harmonisation workflow;
• allowing users to browse and explore the results in an intuitive and user-friendly way, obtaining a comprehensive overview of the collected information, via the computation and visualisation of various metrics and comparative reports.
