Timeline Central Concepts
The notion of Timeline has been used informally in spacecraft operations software for some time, but it has not heretofore been formalized and unified either syntactically or semantically. In this work, the Timeline has been formalized and unified so that the commonality can be exploited to reduce the cost of developing...
