Development History

 

The development history is an ordering which reflects information about what version of an object is used to create a new version of a (possibly different) object. The new version is then called the child; the original version is the parent of the new version. As one can use something several times to create something new, the development history is also a partial order.

There is a natural constraint that the parent must be created temporally before the child. This constraint can be checked using the temporal history as long as the parent and the child belong to the same object. (In the case where another object provides the parent, the constraint can be checked using the command history.)
