+1 to follow patterns that have been already established ;) The solution proposed by Antoine and supported by DCAT-AP and GeoDCAT-AP might be included as example in the DQV document, as a new sub-section of "Example Usage" which we might title, "Express that dataset's metadata is compliant to a metadata standard / application profile" Does this make sense? A further consideration: here we are discussing a statement about the quality of metadata, not about the quality of the dataset. That makes me wonder if we need to include in the DQV's scope other kind of statements pertaining to the quality for metadata, for example, to state the results of metrics on metadata quality. If we consider a full-fledge metadata quality in the DQV's scope, I would suggest to make it explicit, for example, by adding dcat:CatalogRecord besides dcat:Dataset/ dcat:Distribution in the top orange block you find DQV concept Diagram [1]. What do you think?
