Dimension type: temporal

[jstcki]

Temporal dimensions could be inferred by their data type alone but ideally, there's more information

• period vs. point in time (year, quarter, month, day etc. vs. timestamp)
• time interval (monthly, 3 days, 10 min etc.)

[ktk]

• Temporal scale
• is the first question the question about the duration of a particular period/point in time?
  • if so, we might use ISO 8601 duration directly attached to the shape of the dimension
• Resolution might be attached directly to the shape
