  2. What and Why?

    Fun and profit

  3. Statistical Data on the Web (Characteristics)

    • Heterogeneous
    • Decentralized
    • Structured
    • High volume
    • Formats (e.g., CSV, Excel, PC-Axis, SDMX-ML, XML)

    Clean? Synchronised? Comparable? Provenance? Trustable? Analyses?

    • strong correlations
    • predicting or forecasting possible outcomes
    • Investigating the WHYs
