The Dutch government program, Netherlands in Open Connection, and the OpenDoc Society cosponsored the two-day ODF “plugfest” at the Royal Library in The Hague, 15-16 June 2009,  where vendors and open source projects were able to test ODF capabilities with each other in real-world, collaborative scenarios. OASIS TC chairs, Bart Hanssens, (ODF Interoperability and Conformance TC), and Rob Weir (co-Chair ODF TC), participated and delivered presentations.  The details are posted here. The 'plug-fest' was notable for the broad participation from industry and open source communities. Participants included representatives from Microsoft, IBM, Google, Sun Microsystems, Oracle, Red Hat, OpenForum Europe, Feng Office, EuroOffice, AbiWord, OpenOffice, Dialogika, and open source communities. During the closing session, participants were invigorated, and declared the effort a success. Future work will continue in a 'virtual plugfest' format, with potential face-to-face gatherings planned for later in 2009.
