Establishing version control for a document may be thought of as creating a new object of the type 'Document under version control' and using the existing document as the initial version. Imposing version control is an action that cannot be undone.

• Choose the document to be put under version control and
• click  Version   to impose version control on the selected document.

This is indicated by a few changes in the document's entry in the folder listing:

• A version number is inserted after the document name,
• Your user name is given as the name of the owner of the document,
• In the 'Actions' menu of the document the [Revise] action is offered instead of [Replace].

There are a few subtle effects on how BSCW actions affect a document under version control:

Clicking the document name or the icon downloads the current version.

Also actions such as  Convert   or  Archive   affect only the current version.
