• Abstract from Shigeru Watari, Morphe: A Constraint-Based Object-Oriented Language Supporting Situated Knowledge (.ps.gz), Sony CSL technical report SCSL-TR-94-021, July 1994:

  This article introduces Morphe, a programming language aimed to support construction of open systems. In open systems, the programmer cannot completely anticipate the future use of his programs as components of new environments. When independently developed systems are integrated into an open system, we eventually have inconsistent representations of the same object. This is because knowledge about the world is partial and relative to a perspective. We show how Morphe treats relative (and eventually inconsistent) knowledge by incorporating the notions of situations and perspectives.
