content_revision

Content Repository : content_revision

 

Overview

Content revisions contain the data for content items. There is a many to one relationship between content revisions and content items. There is at most one "live" revision for every content item though. For example, there may be 5 revisions of the review for the movie "Terminator," yet only one of these may be live on the website at a given time.
