The central theme of the When 2.0 conference is time, and how it relates to different services and applications. In one extrapolation of this, Mitch Kapor, president and chair of the Open Source Applications Foundation, talked about "stamping" tasks or events, or annotating them with meaning in time, with a beginning and end, a structure and notes. Without giving much more detail, he said this functionality will be part of an upcoming version of an open-source personal identify manager code-named Chandler. Chandler integrates calendar, e-mail, contact management, task management, notes and IM.
