fyi -------- Original Message -------- In case you haven't yet seen the announcement: W3C is pleased to announce the creation of the Uncertainty Reasoning for the World Wide Web Incubator Group [1] to better define the challenge of working with incomplete knowledge. The group expects to identify the elements of uncertainty, produce use cases, and create the fundamentals of a way to represent and reason when truth or falsehood is inapplicable or unknown. The group is sponsored by W3C Members Image, Video and Multimedia Systems Lab, McDonald Bradley, MITRE, National ICT Australia (NICTA), the University of Amsterdam and the University of Bristol. W3C Members may use this form to join the group [2]. Read about the Incubator Activity [3]. -- http://www.w3.org/News/2007#item40 Clearly there is some overlap with RIF, in both membership and subject matter. The Incubator Group (XG) system can function as a pre-cursor to a Working Group, so this effort can merge into RIF at some point in the future when are ready for it, if that seems to be where it fits best. -- Sandro [1] http://www.w3.org/2005/Incubator/urw3/ [2] http://www.w3.org/2004/01/pp-impl/40302/join [3] http://www.w3.org/2005/Incubator/
