Dear Werner, This time about https://www.w3.org/2013/dwbp/track/issues/224 The current DQV spec for the element dqv:expectedDataType is wxsd:anySimpleType as range: http://w3c.github.io/dwbp/vocab-dqg.html#dqv:Metric In our earlier discussion Jeremy had asked: >> c. daq:expectedDataType >> >> This property from DAQ is defined to have range xsd:anySimpleType. While it seems useful to define the expected data type for a metric, a simple type may too narrow: in many cases a metric will be determined on a data record or a subgraph. > > It will be taken into consideration - although I’m not sure it works well with data cube. Please can you provide us (or me) with an example where a quality metric returns a data record or sub graph? > I think I would have to re-iterate this question. It seems that your original wording refers to case where a metric is based on data records or subgraphs as input. But dqv:expectedDataType is for the expected datatype for the output of the metric. Have you got examples where the output would be a record? (especially considering that as per our proposal for Issue 222 [1] we would keep to 'atomic/simple' metrics) Thanks for your feedback, Antoine [1] https://www.w3.org/2013/dwbp/track/issues/222
