Description Eike Stepper CLA 2010-10-10 15:11:12 EDT 
In CDO the URI fragments represent the CDOIDs of CDOObjects. 
The current format of the fragment is:

	CDOID.getType().ordinal() "/" CDOID.value                 // If CDOID.getType() != Type.OBJECT
	-InternalCDOIDObject.getSubType().ordinal() "/" CDOID.value                 // Otherwise
	
That's hard to read, to parse and to use as a key in many environments (e.g. file system).

Come up with a better format.

Comment 2 Eike Stepper CLA 2010-10-10 15:20:20 EDT 
The new format involves a single character as a type/subtype prefix for the id value (no slash anymore!):

  public enum Type
  {
    NULL('N'),
    OBJECT(' '), // Superceded by ObjectType.getID()
    EXTERNAL_OBJECT('E'),
    DANGLING_OBJECT('D'),
    EXTERNAL_TEMP_OBJECT('e'),
    TEMP_OBJECT('t'),
    META('M'),
    TEMP_META('m')
}

  public enum ObjectType
  {
    LONG('L'),
    STRING('S'),
    LONG_WITH_CLASSIFIER('l'),
    STRING_WITH_CLASSIFIER('s'),
    UUID('U')
}

The following methods have been updated accordingly:

	CDOIDUtil.write(StringBuilder, CDOID)
	CDOIDUtil.read(String)
