Interval Representation and Type Relationships
So far, we have dealt with time points and durations expressed via closed-closed or closed-open characteristics. We have shown how to model unbounded validity. The focus has been on the transformation rules across the representations. This chapter deals with the duration interval positions and interaction principles between multiple representations. These interaction characteristics are widely used in the temporal environment by examining the evolution of the object’s states and changes. The emphasis must be on collision detection and undefined state identification. As we will describe in the first part of this chapter, interval interaction types form a tree structure summarizing possible interval ...
