Dear All, Again we are in a position where I still have no news to report on the layered notion of interoperability. Tom: do you have any developments that you can share with this list? For now, I'd like to cancel tomorrow's call, and reschedule it for Thursday August 14 (usual time, 7am US pacific coast). Please let me know if the new proposed date works for you. As before, I encourage you to contribute to the discussion [1], taking place on the dc-architecture list, that Tom Baker has sent pointers to. Thanks, -John [1] http://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0805&L=dc-architecture&P=1835
