For example, try this in PyCrust (Test -> Show Pycrust debugger):

 >>> import wx
 >>> view = wx.GetApp().repository.view
 >>> import osaf.contentmodel.ItemCollection
 >>> ic = osaf.contentmodel.ItemCollection.ItemCollection(view=view) 

Since the ItemCollection class (in 
parcels/osaf/contentmodel/ItemCollection.py) has its myKindPath 
attribute set to "//parcels/osaf/contentmodel/ItemCollection" and is a 
subclass of ChandlerItem, the constructor determines the right kind to 
use.  Its initial values are all set as well.
