The document discusses open data and its potential for innovation through new applications. It describes how open data from the Dutch tax office could be used by developers to create useful applications for citizens, giving examples like a calendar app or one providing legal procedures based on life events. The document notes that while some government data is already available online through sites like data.overheid.nl, questions remain around who owns the data, how it will be published, and how applications will be developed. The overall message is that open data can come alive and drive innovation when used by outside developers to create new applications for public benefit.
