National Archives of Australia releases Xena 4.0

digipres writes: "The National Archives of Australia has had a long commitment to open standards, believing that standards based formats offer the best opportunity for the long term preservation of digital information. Their Xena digital preservation software is free and open source, and the version 4.0 release coincides with the publishing of the new Xena web site at http://xena.sourceforge.net/
Is this how you would treat records that must be understood 500 years from now?"
