Xena

Xena is open-source software for use in digital preservation. Xena is short for XML Electronic Normalising for Archives. Xena is a Java application that was developed by the National Archives of Australia. It is available free of charge under the GNU General Public License. Version 6.1.0 was released 31 July 2013. Source code and binaries for Linux, OS X and Windows are available from SourceForge. However, as of 2018, it is no longer maintained or supported. Mode of operation Xena attempts to avoid digital obsolescence by converting files into an openly specified format, such as ODF or PNG. If the file format is not supported or the Binary Normalisation option is selected, Xena will perform ASCII Base64 encoding on binary files and wrap the output in XML metadata. The resulting .xena file is plain text, although the content of the data itself is not directly human-readable. The exact original file can be retrieved by stripping the metadata and reversing the Base64 encoding, using an internal viewer.
