The NAA believes that that open source formats will better assure long term access to documents when compared to closed, proprietary file formats. "The project team decided that using proprietary data formats for archiving would not ensure files could be opened and replicated on the computer systems of the future." "Cross platform development is really important ... Who knows what platform most people will be using in 30 years time?" said Simon Davis, an assistant project manager for NAA.
The National Archives of Australia (NAA) is using the OpenOffice.org file format for archiving according to an article in ComputerWorld.
The NAA is developing an XML based application, called XENA (XML Electronic Normalising of Archives), to aid in archving and will release the software under the GPL so that others can benefit from this work too.
