Incomplete Objects - A Data Model for Design and Planning Applications
Summary: Introduces OR-objects to model incomplete specifications as possible-worlds for design/planning data. Explores interpretations vs the database, hypothetical queries, complexity, and gaps like staged coexistence, separation of representation and interpretation, and nondeterminism.
