The eighth ODF plugfest will return to Brussels (Belgium) on April 19th/20th 2012, this time hosted by Microsoft Corporation and supported by OpenDoc Society. The ODF plugfests are an ongoing series of vendor-neutral events, bringing together implementers and stakeholders of the standard. The goal is to achieve maximum interoperability by running scenario-based tests in a hands-on manner and discuss new and proposed features of the Open Document Format specification. Lead architects from commercial and open source products, members of the OASIS ODF TC's and technical experts from national and regional governments will be present. Previous plugfests were held at The Hague (Netherlands), Orvieto (Italy), Granada (Spain), Brussels (Belgium), Borough of Windsor and Maidenhead (UK), Berlin (Germany) and Gouda (The Netherlands).
