a relationship between model elements at different semantics levels, such as analysis and design
(v) A repetitive process (iterative or cyclical) used to test the preliminary design, make changes if necessary, and determine if the design meets the goals of the project. Models are used to analyze and visualize the design. Refinement drawings are used to analyze the design in its current stage of the design process.
generally, an iterative way of improving the accuracy, or resolution of a map by making use of constraints, see three-dimensional projection matching.
A model of a system that adds more details (metrics, drivers, functional relationships).
a property of a resource which shares the meaning of a particular element but with narrower semantics.
