AN IMPORTANT COMPONENT OF THE NEXT GENERATION OF SOFTWARE ENVIRONMENTS WILL BE AN OBJECT MANAGEMENT SYSTEM FOR HANDLING THE NUMEROUS AND DIVERSE KINDS OF INFORMATION THAT THEY CONTAIN. ONE ASPECT OF OUR RESEARCH ON OBJECT MANAGEMENT FOR ARCADIA ENVIRONMENTS IS BASED ON THE VIEW THAT ALL ENTITIES POPULATING AN ENVIRONMENT SHOULD BE INSTANCES OF ABSTRACT TYPES. THIS PAPER DESCRIBES OROS, A TYPE MODEL THAT WE ARE DEVELOPING THROUGH A TOP-DOWN EFFORT TOWARD DEFINING REQUIREMENTS AND SPECIFICATIONS FOR TYPE SYSTEMS SPECIFICALLY TAILORED TO SUPPORT SOFTWARE ENVIRONMENT TYPING NEEDS. WE PRESENT A SERIES OF OBSERVATIONS CONCERNING PROPERTIES OF THE OBJECTS THAT POPULATE ENVIRONMENTS AND WE DESCRIBE THE CHARACTERISTICS OF THE CURRENT OROS TYPE MODEL ARISING FROM THOSE OBSERVATIONS. THE USE OF OROS AND THE VALUE OF A TYPE MODEL IN ENVIRONMENT OBJECT MANAGEMENT ARE ILLUSTRATED THROUGH EXAMPLES.
