Dear Thomas:

The OOPSLA '89 paper was indeed not on the web.
It is now the third entry in:
http://www.ccs.neu.edu/research/demeter/papers/publications.html

Or
http://www.ccs.neu.edu/research/demeter/biblio/oopsla89.html

We worked already then on separation of structure and behavior and traversals:

============quote
We gain the following advantages in separating a program into
two tiers:
\bi
\item
A separation of concerns and a division of effort:
The structural aspects are written and checked first before the details
of object manipulation are specified.

\item
Reusability: The structural definitions (upper tier)
can be used with different programming languages.

\item
Ease of learning: The upper tier
allows students the ability to explore concepts without
having to deal with the underbrush of a programming language syntax.
\ei

Object Traverser Objective

The student will write an object traverser (skeleton) for each class
defined in the class dictionary.
This skeleton is the starting point for many application programs.  It is automa
tically
generated by the Demeter system but the student should practice generating it
by hand.
============== end of quote
