Descriptive Intermediate Attributed Notation for Ada
DIANA

    (DIANA) A formerly de facto standard
   intermediate language for Ada programs, developed by Goos
   and Wulf at CMU in January 1981.  DIANA is an attributed
   tree representation, with an abstract interface defined in
   Interface Description Language (Nestor, Lamb and Wulf, CMU,
   1981; Snodgrass(?), 1989(?)).  DIANA resulted from a merger of
   AIDA and TCOL.Ada.  At the present (2001) it is no longer
   used by the major ADA compilers

   ["DIANA - An Intermediate Language for Ada", G.T. Goos et al,
   LNCS 161, Springer 1983].
