Activity (and other) costs (Module V, section 3). Aggregate object. A collection (Module V, section 2). A composition is a structured aggregate. Array (Chapter 4, section 1). Assemble. A polymorphism of process and the part of relationship (Module V, section 4). Assemble emerged from a process that made an item a part of an aggregate in step with the flow of time. Similarly disassembly cuts the relationship between an aggregate and its parts, so that the part does not remain a part of the aggregate after disassembly has occurred. Thus disassemble is also a process, but it is a polymorphism of the exclude relationship (near the top of figure 116). Polymorphisms of disassemble will tell us how an aggregate is picked apart – explosively, all at once, or in steps – perhaps even one item at a time. Attribute. A kind of object property that is also a subtype of domain . It is a relationship between an object class and a subtype of a domain that consists of a single value at any given time (Chapter 3, section 2). Beginning and ending moments of an event (both are subtypes of moment ). Borel object. A generalization of the concept of array , useful for categorization and segmentation of objects and state spaces – a power set of values, or an infinitely large power set of ranges (see Module V, section 1). Bounds (Chapter 3, section 2). Capacity. A kind of cardinality constraint (see Module V, section 1).
