The data navigator can render (output) the XML of objects old versions.

Objects old versions are identified by 'versions identifiers' composed by the object id and the UTC date-time of when the old version was created Versions identifiers are represented as string with the decimal id followed by 'v' followed by the date-time, e.g.:

  3560v2010-08-11T16:05:05.94Z

is the version created on August 11th, 2010 at 4:05:05.95 PM of the object with id 3560. (The 'Z' can be omitted - the date-time are assumed to be UTC).

The commands ../do.ashx?cmd=objsnav and ../do.ashx?cmd=feed can accept in their 'ids' parameter a mixture of object ids and version identifiers, and they'll output the corresponding objects and objects old versions - e.g.

  ../do.ashx?Cmd=feed&name=display&ids=3560v2010-08-11T16:05:05.94Z,3555

will output the object old version of the example above and the object with id 3555 together, formatted using the 'feed_Display' configuration.

The XML of an old versions is identical to the one of a normal object except that:

•references to objects that no longer exists are stripped;

•there is a new element 'nav:versionCreation' that details when the version was created and by whom, e.g.:

It is not possible to create ZIP feed containing old versions - attempts to do so causes the error 1314: 'It is not possible to use old versions in a ZIP feed'.
