Hi, I believe that using them together is beneficial especially when an existing dataset available for example in CSV is converted to RDF. In this scenario I usually describe the resulting RDF dataset in VoiD and the original dataset in DCAT while linking them together using dct:source something like: :void-dataset dct:source :dcat-dataset. :dcat-dataset dcat:distribution :dcat-dist. :dcat-dist dcat:accessURL <url-to-the-csv-file> using this representation, the converted RDF representation is linked to its source and therefore can be checked and validated. For example have a look at: http://vmsgov03.deri.ie:8080/data-cube-searcher/index.html?query=howth%20primary%20schools notice the link to the original CSV file that is enabled by the link from void to dcat datasets. Hope this helps!

There seems to be a large amount of overlap between the two specifications. Are there plans on combining the specifications?
