from 1994: Subjectivity in Object-Oriented Systems Workshop Summary. heard about it via the object-composition list.

Subjectivity in object-oriented systems is a new research

much discussion of fundamental concepts and issues, as
well as of perceived needs for subjectivity and models for
realizing it. The discussion is summarized here, and a list
of issues that were identified during the workshop is
presented.
