The second OpenDocument format (ODF) plugfest will take place in Orvieto, Italy, on 2-3 November 2009. This two-day ODF interoperability workshop aims to bring together the key vendors and organisations implementing open document format, in order to achieve full seamless interoperability for the entire feature set of ODF across all suppliers, platforms and supported technologies.

The workshop is meant for people who write and architect the code to handle the actual ODF in applications, such as desktop editors and viewers, online applications develppers, etc. Participants should ideally represent every major team behind the various competing ODF products, their direct management and community leaders, as well as the members of the ODF OIC committee.

The workshop will take place at the Fondazione Cassa di Risparmio Di Orvieto.

The event is organised by the Dutch government programme Netherlands in Open Connection and OpenDoc Society together with the OASIS ODF TC, OASIS ODF OIC TC and ODF Adoption TC.
