We are happy to announce that WikiSym 2013 will take place in Hong Kong on Aug 5-7, 2013. WikiSym will co-locate with a new sister event, OpenSym 2013. (WikiSym will be followed by Wikimania 2013, also in Hong Kong.) Research paper submission deadlines for WikiSym + OpenSym will be in March 2013. WikiSym + OpenSym 2013 will emphasize the open collaboration aspect of WikiSym both for researchers as well as practitioners. Open space will play an important role. More details to follow, stay tuned!
