Not sure if anyone's heard of CalConnect before, but Apple just joined it: http://www.macnn.com/articles/06/08/08/apple.joins.calconnect/ http://www.calconnect.org/publicity/060807applejoinscalconnect.pdf They describe themselves: "The Calendaring and Scheduling Consortium. The Consortium is focused on the interoperable exchange of calendaring and scheduling information between dissimilar programs, platforms, and technologies. The Consortium's mission is to promote general understanding of and provide mechanisms to allow interoperable calendaring and scheduling methodologies, tools and applications to enter the mainstream of computing." They don't seem to know anything about microformats given a search of their site, so perhaps someone should ping them?
