Indicators for an open data impact assessment

While the impact of open data has been studied before, typically on an ad hoc basis, structured methods and indicators to measure its impact and the possibilities of basing these indicators on existing datasets still need to be explored and are the subject of this study.This report is the second step in defining the methodology for a European-wide assessment of the impact of open data. The study series aims to create an interactive monitoring tool for open data impact assessment.This second study aims to provide theoretical input to develop a methodology that analyses the impact of public data resources, focusing on the different impacts to be considered and the indicators that could quantify them. This report uses the results and conclusions presented in the first study on 'rethinking the impact of open data' as a foundation. The results of this study could be incorporated into a third study, where a draft methodology to measure the impact of open data could be developed and piloted.
