An anonymous reader writes with news that the Open Document Format 1.2 specification has finally been approved. "The most important improvement to ODF 1.2 is the newly built spreadsheet support. The old format was buggy and had a lot of legacy problems. Therefore the new spreadsheet module was written from scratch. 'A complete clean room implementation of the spreadsheet formula was built,' said [Michiel Leenaars, director of the Internet Society Netherlands]. ... Another important improvement in ODF 1.2 is the support for Resource Description Framework (RDF) metadata, a W3C standard model for data interchange on the Web. ... Instead of only being able to link to a URL, RDF allows users to link text in documents to other things like a V-Card or a calendar item. Companies can use this technology to structure their workflow."
