Xena (software)

For other uses, see Xena (disambiguation).

Xena is open-source software for use in digital preservation. Xena is short for XML Electronic Normalising for Archives.

Xena is a Java application 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.

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.

Features

Platforms supported by Xena are Microsoft Windows, Linux and Mac OS X.

Xena uses a series of plugins to identify file formats and convert them to an appropriate openly specified format.

Xena has an application programming interface which allows any reasonably skilled Java developer to develop a plugin to cover a new file type.

Xena can process individual files or whole directories. When processing a whole directory, it can preserve the original directory structure of the converted records.

Xena can create plain text versions of file formats such as TIFF, Word and PDF, with the use of Tesseract (software).

The Xena interface or Xena Viewer can be used to view or export a Xena file (extension .xena) in its target file format. These files contain the normalised file as well as any extra information relevant to the normalisation process. The Xena Viewer supports bulk export of Xena files to target file formats.

Xena can be used via its graphical user interface or the command line.

For Xena to be fully functional, it requires a local installation of the following external software:
