Introducing COmega is a good overview of what is probably the most obviously startling thing about COmega -- it's attempt to bridge XML / Object / Relational worlds with built-in syntax. I'm not sure that this is going to be COmega's biggest contribution to the mainstream (I suspect that it's threading techniques using “chords” may prove to be more important), but it's certainly interesting. Dare promises to visit E4X, which combines XML handling with JavaScript and is, in my opinion, a better match for many XML processing scenarios, in his next article.
