RE: ISSUE-124 - deprecate January and Year

As I've been working on two separate groups of issues in OWL-Time, I've created two branches with names to reflect these. So the work described below which was initially in a branch simon-time is now in simon-time-individuals 
See:

Subject: RE: ISSUE-124 - deprecate January and Year

OK – so take a look in the RDF file for OWL-Time in the branch simon-time [1] 

Following the examples of January and Year from 2006 OWL-Time, I've created resources for 1. all of the months-of-the-year as subclasses of DateTimeDescription 2. all of the basic time durations as subclasses of DurationDescription

I've also 

3. shown how Year, Month, Week ... etc can also be conceived as subclasses of the new class Duration, for example 

:Year
  rdfs:subClassOf :Duration ;
  rdfs:subClassOf [
      rdf:type owl:Restriction ;
      owl:hasValue :unitYear ;
      owl:onProperty :unitType ;
    ] ;
  rdfs:subClassOf [
      rdf:type owl:Restriction ;
      owl:hasValue 1 ;
      owl:onProperty :numericDuration ;
    ] ;
.

In addition to the original subclassing from DurationDescription. 

4. shown how January, February, March ... etc can be conceived as individuals from a new class MonthOfYear, which follows the precedent of DayOfWeek which was already there. So for example, the complete description of April looks like 

:April
  rdf:type owl:Class ;
  rdf:type :MonthOfYear ;
  rdfs:label "April"@en ;
  rdfs:subClassOf :DateTimeDescription ;
  rdfs:subClassOf [
      rdf:type owl:Restriction ;
      owl:hasValue :unitMonth ;
      owl:onProperty :unitType ;
    ] ;
  rdfs:subClassOf [
      rdf:type owl:Restriction ;
      owl:hasValue "--04" ;
      owl:onProperty :month ;
    ] ;
  skos:prefLabel "?@5;L"@ru ;
  skos:prefLabel "#(1JD"@ar ;
  skos:prefLabel "4"@ja ;
  skos:prefLabel "4"@zh ;
  skos:prefLabel "Abril"@es ;
  skos:prefLabel "Abril"@pt ;
  skos:prefLabel "April"@de ;
  skos:prefLabel "April"@en ;
  skos:prefLabel "April"@nl ;
  skos:prefLabel "Aprile"@it ;
  skos:prefLabel "Avril"@fr ;
  skos:prefLabel "KwiecieD"@pl ;
.

So each month is both a class and an individual. 
Note that I also added multi-lingual labelling for months and days, scraped from DBPedia, using the skos:prefLabel annotation. 

5. In the branch these are all in the main namespace. 

So there are a few questions here: 
(i) Should months be both classes (following the precedent from 2006) and individuals (following the pattern from DayOfWeek)
(ii) Should the duration individuals be both DurationDescription and Duration (don't see why not)
(iii) what namespace for all these
(iv) what property to be used for multi-lingual labels
