A Baseline represents the state of a Digital Thread Project and its contents at a specific point in time. A Baseline is identified by its unique timestamp. Users can create new baselines and compare baselines to review digital thread relations created, updated, and deleted between the baselines. Users can also compare a baseline with the current timestamp (Now) to view changes in the Digital Thread Project since the last baseline, or any given baseline. The Baseline feature is accessible from the Baselines tab of the Digital Thread Project Dashboard, as shown in Figure 1 below. Two (2) sub-tabs - Manage and Compare - are used for managing and comparing baselines, as shown in Figures 1 and 2 below.
