>Are you aware of a 'standard' way to provide basic dataset statistics using DQV or any other RDF vocabulary? e.g. minimum/maximum(/average) values for specified dimensions? I'm not seeing anything obvious in DQV or QB :-( I guess it might be a dqv:Metric but I wonder if you could provide guidance on how this might look? I am not aware of anything except the examples mentioned by @agbeltran for the statistics oriented to RDF datasets, perhaps @makxdekkers knows more ?!?. Anyway, I guess there is more than one way to do it. For example, using RDF data cube you can define your own qb:DataStructureDefinition. if you want to describe statistic of datasets such as Average, Max, Min for the "fields" in the dataset, you might define a qb:DataStructureDefinition whose dimensions/components include - the considered dataset - the considered field - the considered operator ( i.e. Average, Max, Min.. etc) - the actual measures If you provide statistics as quality indicators you can think of using DQV qualityMeasurement, for example defining a new dqv:dimensioni for each pair of field and operator. -- GitHub Notification of comment by riccardoAlbertoni Please view or discuss this issue at https://github.com/w3c/dxwg/issues/84#issuecomment-469071937 using your GitHub account
