I have been using Rational Application Developer v6 since the early WP5.1 beta days(November 2004).
I updated my install to v220.127.116.11 and found the Domino SDO functionality, and I was pleasantly surprised.
I have been drinking the SDO Kool-Aid for the past year or so, and it was refreshing to see it implemented for my favorite document centric store (NSF). I will have some updates on issues and successes with using the SDO in articles and future blog posts, as I play with the feature more. One of our consultants, Chris Riner, has been playing with it at my customer site and finds it useful with the WSIWYG and rapid application development functionality combined with JSF.
