There are no Duration properties.  I recently tried a step down the path of 
adding them and got as far as supporting

    \set Staff.parserTestDuration = \breve
    \set Staff.parserTestDuration = ##{ 4. #}
    \set Staff.parserTestDuration = \duration 4.

before deciding to leave the existing Moment properties as they are and provide 
\musicLength [1] to clear ly code of #(ly:make-moment…) cruft.

I'm not saying that Duration properties couldn't or shouldn't be added; I'm 
just warning that they're not a ready option.
