DeltaV: Adding Versioning to the Web

Documents change over time. Whether they are word processing documents, spreadsheets, Web pages, or source code, the process of creating the contents of these documents involves change over time. It is frequently useful to track changes to a document over time, as this permits tracking who made a specific change, backing-out undesirable changes, recording why a specific change was made, and the ability to know what the document contents were at a specific point in time. Change tracking capabilities gives greater control over change, since changes are now explicitly recorded, and an archive of important document versions.
