I would like to point out the need of an additional property for the dcat:Distribution class. It would be used to indicate if the access to data refereed by dcat:accessURL is either 'direct' or 'indirect'. We discussed it time ago, but we didn't modify the draft on the wiki.

Some examples:
-> Direct: accessURL points to a WebService, RSS, XLS, or XML, which
offers the distribution directly.
-> Indirect: accessURL points to a REST WebService or API
documentation (how to use it, parameters, etc) | an XML zipped

We have solved this issue using the property dcterms:type and a couple of concepts (indirect-access, direct-access) to set type of each distribution.

[] a dcat:Distribution ;
   dcat:accessURL "http://.../file.xml"^^xsd:anyURI ;
   dcterms:type <http://purl.org/ctic/dcat#accessMode-direct> ;
   ...

[] a dcat:Distribution ;
   dcat:accessURL "http://.../file.zip"^^xsd:anyURI ;
   dcterms:type <http://purl.org/ctic/dcat#accessMode-indirect> ;
   ...
