In 2007 Wendell Piez and I wrote a conference paper on this topic. "Separating
Mapping from Coding in Transformation Tasks".

The slides are available at:
http://www.mulberrytech.com/papers/MappingTransformations/index.html
and there is a sample mapping specification at:
http://www.mulberrytech.com/papers/MappingTransformations/dhqmap.html

We at Mulberry still use this method. We find that, in general, using this
method, the mapping takes about twice as long as the coding. Total development
time is less than if the mapping step is "skipped" (because the mapping is
never skipped, if the programmer starts writing code immediately the mapping
is hidden, but must still be done).
