Conclusion

!   Data is fuelling the knowledge-based economy and society !   Global standards enable integration and re-assembling data and apps

!   Current applications show-cases mainly single-source datasets !   Next steps: interlinking and cross-referencing data from multiple

sources

!   Further research into large-scale semantic data management: multiple modalities (graphs, streams, relations), data quality, privacy, provenance, trust, access rights

!   Commercial applications leveraging open gov’t data (in combination with scientific or proprietary data) can bring added value for citizens
