OASIS announced that its members have approved the Open Document Format for Office Applications (OpenDocument) v1.0 as an OASIS Standard, a status that signifies the highest level of ratification. OpenDocument provides a royalty-free, XML-based file format that covers features required by text, spreadsheets, charts, and graphical documents. OpenDocument provides a single XML schema for text, spreadsheets, charts, and graphical documents. It makes use of existing standards, such as HTML, SVG, XSL, SMIL, XLink, XForms, MathML, and the Dublin Core, wherever possible. OpenDocument has been designed as a package concept, enabling it to be used as a default file format for office applications with no increase in file size or loss of data integrity. Future plans for the OASIS OpenDocument Technical Committee include extending the standard to encompass additional areas of applications and users, as well as adapting it to incorporate ongoing developments in office applications. All those interested in advancing this work, including governments, open source initiatives, educational institutions, and software providers, are encouraged to participate in the Committee. OASIS hosts an open mail list for public comment and the opendocument-dev mailing list for exchanging information on implementing the standard. http://www.oasis-open.org
