DUV: dct:identifier used with URI references instead of literals

Dear DWBP WG,

I noticed that in the examples, dct:identifier is used with a URI 
reference, although its range is rdfs:Literal.

E.g., see Example 1:


:stops-2015-05-05
         a dcat:Dataset ;
         dct:title "Bus stops of MyCity" ;
         dct:identifier <http://dx.doi.org/10.0902/1975.16>
         dct:issued "2015-05-05"^^xsd:date ;
         pav:version "1.0" ;
         dct:publisher :transport-agency-mycity ;
         dct:creator :bus-association-mycity ;
         duv:hasDistributor :transport-agency-mycity ;
         disco:fundedBy :bus-association-mycity ;
         dct:created "2015-05-05"^^xsd:date ;
         .


This should be re-written as:


:stops-2015-05-05
         a dcat:Dataset ;
         dct:title "Bus stops of MyCity" ;
         dct:identifier "http://dx.doi.org/10.0902/1975.16"^^xsd:anyURI ;
         dct:issued "2015-05-05"^^xsd:date ;
         pav:version "1.0" ;
         dct:publisher :transport-agency-mycity ;
         dct:creator :bus-association-mycity ;
         duv:hasDistributor :transport-agency-mycity ;
         disco:fundedBy :bus-association-mycity ;
         dct:created "2015-05-05"^^xsd:date
         .


Moreover, Example 1 shows some syntax errors present also in the other 
examples:

1. The semicolon (;) is missing in some examples after the URI reference 
used with dct:identifier.

2. In all the examples, most of the groups of (Turtle-serialised) RDF 
statements end with ";" + new line + ".". The semi-colon should be removed.
