Dear Jeremy, Thank you for your answer [1]. Unfortunately, since I am not subscribed to public-csv-wg-comments, I only found it now. Your example [2] is interesting. I am wondering whether based on your work it would be possible to have a more compact representation of a qb:DataSet with: 1) A definition of a qb:DataSet with a link to the metadata of a CSV file and a link to the CSV file (or links to rows in a CSV file) 2) A definition of a qb:DataStructureDefinition with links to instances of qb:DimensionProperty, qb:MeasureProperty, and qb:AttributeProperty, each with links to columns in the CSV file. Given the data and metadata one could have an algorithm similar to the QB Normalization algorithm [3] to translate this compact to a normalized qb:DataSet. Best Benedikt [1] ------------ (cross-posted from our issue tracker on Github: https://github.com/w3c/csvw/issues/509 <https://github.com/w3c/csvw/issues/509> . if you have a Github account, please feel free to add your comments there) Hi Benedikt - I always had an eye on using the [RDF Data Cube][1] as output from the CSV to RDF conversion. To illustrate use of the RDF Data Cube for converted CSV data I have created a real example - based on historical weather observations published by the [Met Office][2]. The example is described [here][3]. Please let us know if this illustrates what you need to know.
