- 20. Process • What are possible paths for organizations that want to make open data available? • Start small or think big? • What organizational and technical success factors exist? 9
- 21. Quality and provenance • Within the publishing organization, how is data quality assured, maintained and communicated? • How can developers ascertain that the data used has sufficient quality? • What are limitations to the sustainability of applications built on open data? 10

- 26. • How best to provide access to data so it can be most easily reused? • How to enable the discovery of relevant data within the multitude of available data sets? • How to enable applications to integrate data from large numbers of formerly unknown data sources? 12
