History
The Meridian history feature maintains all changes to vault data over time, including revisions to documents. History is enabled or cleared for each vault by a System Administrator.
The last released revision of a document is always the default one shown in a vault. However, by using the Show Revisions command, you can see all previous revisions and their effective dates. History also allows you to view the entire vault at a particular moment in time and to save a shortcut to that moment, called a baseline. When you view history, all documents and their revisions, property values, and references appear as they were at that point in time. The view includes all released documents at that point in time. New documents and copies of released documents that are under change and have not yet been released are not shown.
Support for baselines in PowerWeb must be enabled by a System Administrator.
