Today at the AICC meetings in San Diego, Bill Shook of Boeing did a really nice overview of S1000D and it's benefits and relevance for training and elearning. The PowerPoint should be up on the AICC web site in the meetings minutes here in a few days. Hungering for more information on S1000D I stumbled onto a blog while surfing the in-room discussion and the blogosphere at the same time.
I have no idea who Martyn is, but I like the content and comments that go on at his blog on S1000D. The reference links are pretty handy too.
S1000D - "Sense Out of Confusion"
A great place to start your S1000D adventures whether you are in technical documentation or training.
