org.pentaho.platform.api.repository.IContentItem
Construction of a new ContentItem is managed by ContentLocation.newContentItem. This is because there is a parent-child relationship between ContentLocations and content items. To avoid having a content item reach back into it's parent to add itself to the children list, you instead call the content location to construct a content item. A content item cannot exist without a content location. @see ContentLocation @author mbatchel
