These results were obtained with SuperClass & SubClass flags set.

I first started getting suspicious when
    GetData Property type yes | sort
did not contain subClassOf.  

Here are some short outputs
highlighting some of the problems

$ GetData subClassOf type no
  TaxonomicPropertyType
  TransitivePropertyType
# INFO: GetData: count = 2
$ GetData title type no
  Property
  TitlePropertyType
# INFO: GetData: count = 2
$ GetData arcs arcs no
# INFO: GetData: count = 0
$ GetData startingDate type no
  Property
# INFO: GetData: count = 1
$ GetData instanceOf type no
  TaxonomicPropertyType
# INFO: GetData: count = 1
$ GetData instanceOf arcs no

$

Here are a few observations
1. arcs has no arcs
Is that intentional because it's an internal property?
type has no arcs

2. inconsistent type links to Property & its subClasses, e.g.
subClassOf not linked to Property
title is linked to Property

3. "incorrect" type links to ReflexivePropertyType and
TransitivePropertyType and TitlePropertyType.  
I didn't try to check all the links; it just seemed like 
there were way too many (about 110).

4. no domain & range for most properties.
