I must admit I am a little bit perplexed by the use of dcat:accessUrl to describe a dcat:Download. The usage note indicates that:

"""
accessUrl of the Download distribution should be a direct download link (a one-click access to the data file).
"""

It makes me wonder if we should instead be recommending that the URI for the dcat:Download be the actual URI for the download. So for example:

 ex:dataset1 a dcat:Dataset ;
     dcat:distribution ex:download1 .

 ex:download1 a dcat:Download ;
     dcat:accessURL  <http://example.gov/downloads/1> ;
     dct:format "text/csv" .

would become:

 ex:dataset1 a dcat:Dataset ;
     dcat:distribution <http://example.gov/downloads/1> .

 <http://example.gov/downloads/1> dct:format "text/csv" .

See how the intermediary resource (probably a blank node in practice) goes away? I think the same could be said of dcat:Feed.
