the work of the Demeter research group:

My ICSE 2004 paper:
http://www.ccs.neu.edu/research/demeter/papers/icse-04-keynote/ICSE2004.pdf
presents the Law of Demeter of concerns and uses it to explore 
AOSD techniques.

Our TOPLAS 2004 paper:
http://www.ccs.neu.edu/research/demeter/biblio/strategies.html
describes the core algorithms for expressing and 
implementing crosscutting in graphs.

A technical report with Mitch Wand:
http://www.ccs.neu.edu/research/demeter/biblio/new-strategy-semantics.html
provides an easy and precise introduction to traversal strategies.
