If a document is edited simultaneously by several authors or if different variants are to be managed in parallel, you may create two or more parallel version branches of the original document, each having its own ‘current versions’. A new version branch is again a document under version control that starts out from an arbitrary version of the original document. You may also create branches of branches.

• Select   Branch  from the action menu of a document under version control.
• In the version history of the ‘Branch’ form, select the version from which the new branch is to originate by clicking its radio button in the Id column. Enter a name for the new version branch.

The first version of the new branch document is a copy of the root version of the original document in the same folder. The state is also copied, the version number is formed by appending next-branch-number.1. The latter may be changed using   Version Info .

Note:

Copying documents under version control means branching, i.e. a new version branch of the document is automatically generated in the clipboard.

BSCW does not provide any specific support to ‘re-unite’ several version branches that have been modified in parallel. Therefore it is important to have telling change descriptions and to agree beforehand on a document editing and versioning strategy in order to facilitate the process of bringing the different branches together into a single consolidated document.
