Data of the datatype Quantity isn't yet showing up when performing data extension of Commons files via the Commons Reconciliation Service in OpenRefine.
You can test with this small dataset:
- Load this set in OpenRefine
- Reconcile the file names using the Commons Reconciliation Service
- Try to retrieve the values of the exposure time (P6757) and f-number (P6790) properties - currently this will produce two empty columns. Exposure time has a unit, f-number hasn't
For comparison: the Wikidata reconciliation service returns the string(s) without retrieving or displaying the units.
