Item Versioning in IBM Lotus Web Content Management !!!!

Lotus Web Content Management a versioning systems with which authors, designers,
and administrators can track the changes that have been made to specific items or to an
entire library, identify versions of libraries by date or tag, and restore them in the future.

Following options are available to define when an item should be versioned.

• Manual : A version action can be added to a workflow stage to create a new version
  when entering or exiting the workflow stage.
  A version action in a draft stage will not trigger versioning, since a draft
  cannot have versions.
  It is possible to create only one version of the item in a stage.
• Always : A version of an item is created each time you save an item, or, if the item is
  participating in a workflow, each time the item's state changes to published.
• Never: Versioning is never used.

Global versioning strategy is defined in WCMConfigService.properties. These options
are available:
versioningStrategy.Default = always | never | manual
versioningStrategy.AuthoringTemplate = always | never | manual
versioningStrategy.Component = always | never | manual
versioningStrategy.Content = always | never | manual
versioningStrategy.PresentationTemplate = always | never |
manual
versioningStrategy.Site = always | never | manual
versioningStrategy.Taxonomy = always | never | manual
versioningStrategy.Workflow = always | never | manual
You can restore a version by viewing an item's version history and selecting a version to
restore.
