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.

• Chose the Document to be put under version control and
• click  Version Control   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' action.

Beyond that there are a few subtle effects on how BSCW actions affect a document under version control:

Clicking the Document name or the MIME type icon to its left downloads the current version.

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