Ron's notes, IMHO, are far too informal.  Too many goods, shoulds, and
nices.  Notes like this often add to the confusion of ``what is an
object'' rather than explain it.  I'd recommend reading:

    ``Assessing the Quality of Abstract Data Types Written in Ada'',
    D.W. Embley and S.N. Woodfield (Brigham Young University),
    Proceedings of the 10th International Conference on Software
    Engineering, April 1988, Singapore, pp. 144-153, IEE Computer
    Society Order Nuber 849, ISBN 0270-5257, ACM Order Number 592880,
    ISBN 0-89791-258-6.

Embley and Woodfield present a straightforward, machine-checkable
method of measuring the coupling and cohesion of a module (in this
case, Ada package).

Now I know that Ada is not OO, and that data abstraction is but one
aspect of OO, but it's a good start.  If anybody knows of other
published measuring techniques (i.e., metrics) that do take into
account other aspects of OO, please post references.
