Russian Dolls and XML: Handling Multiple Versions of XML in XML

Although providing a high level of flexibility, XML is an ephemeral format. Unlike something like CVS which can store a history of versioned data, XML documents hold a snapshot of data. But could there be a solution?

Overcoming the Challenge of Storing History

There are a number of challenges associated with storing multi-version history data within a single XML file. Ideally, when dealing with documents, changes should be recorded at the word level. It must be easy to extract a version, add a new version into the archive, delete a version from the archive or clone a version within the archive.

This paper proposes a generic XML format to handle multiple versions of an XML document, using the same basic structure as the files which are being archived.

The challenges are greater, but so are the rewards. A multi-version XML file will contain the data in a structured and processable form, opening up the opportunities for more intelligent applications.
