RML Mapping: Fahrgastzahlen BVB

Mapping Structure

• The following columns were mapped as dimensions:
  • startdatum_kalenderwoche_monat (temporal), as it defines the start date of each observation period (week or month).
  • kalenderwoche (categorical), reflecting weekly granularity where applicable.
  • granularitat (categorical), to indicate whether data is weekly or monthly.
  • A derived spatial dimension (RAUM), set to the dataset's context value "Basel-Stadt".
• The measure column is fahrgaste_einsteiger_innen, representing the observed passenger count for each time period.
• The column datum_der_monatswerte was dropped as it is redundant with startdatum_kalenderwoche_monat and not needed for cube structure.
• Code (DefinedTerm) resources are generated for each key dimension to enable consistent dimension value representation.
• No explicit hierarchies or aggregation levels were created beyond the week/month temporal granularity.

Dimensions:

• startdatum_kalenderwoche_monat (temporal) - granularity: week_or_month
• kalenderwoche (categorical)
• granularitat (categorical)
• RAUM (spatial)

Measures:

• fahrgaste_einsteiger_innen (Fahrgäste)
