OTLML makes me think that I need to play more deeply with XML. I need to learn XSL, how to use Xpointers, I really have to spend more time with RDF, and I need to work with SOAP more.

I think I see the difference between things like RSS 0.92 and RSS 1.0, and between OPML and OTLML, now. Not quite sure if I can explain it precisely enough yet, but I have a slight groking of it. The upshot of it is that I really need to throw myself toward the side of latter in both cases.

Back to work.
