My May/June 2004 IEEE Internet Computing magazine "Toward Integration" column is now available. This one, entitled More Web Services Notifications, is a follow-on from the previous column. It covers the WS-Notification spec, which I couldn't cover last time because it wasn't published yet.
Note that, unfortunately, the published version has a minor error in the references, which I've fixed in my online version. The problem is that the real reference 5, which should refer to the WS-Addressing spec, is missing. Doh! With the real reference 5 in place, the references currently listed as 5 and 6 should really be 6 and 7.
As with all my publications, all feedback on this new column is welcomed.
