4.8.5 Accessing an earlier version

BSCW lets you download earlier versions of a Document under version control in two ways: by directly specifying its URL or by picking the version in the Documents's Info page:

• Click    left of the Document's MIME type icon

to display its Info page. It contains a table captioned Version history and, for a Document in a version branch, another table called Related branches. The tables contain one row per version that shows their author, state and date of creations plus any change description available.

• Click its version number in the Id column

to download a version.

You may access (download) an earlier version directly via a URL. General information on the URL of a BSCW object is in section 4.11. For a Document under version control, you have to add its version number to its URL in order to access a specific older version:

;version=<version number>

is appended to the address of the current version of the Document.

Note:

You cannot make any changes to older versions of a Document under version control, unless you branch out from the version that you want to edit (see section 4.8.4) and modify the branch version.
