I'm on about projecting trees from the graph in the interests of
low-surprise user interactions. I wouldn't really consider any
intermediate format so much as data, more as presentational markup.

Don't think that buys you any grace. I'm currently perched on an inch
of seat-edge, the rest being taken up by that there goddaughter of
yours (she grow'd!)

But I think I'd rather issue a reverse

That could well prove quite a challenge, "can't" doesn't figure highly
in the software vocabulary. Typical application problems seem like
they can potentially be solved using virtually any arbitrary set of
tools/languages. The solution might be a Rube Goldberg construction,
but that's enough to demonstrate not-impossibility. But if you can
think of a good example, I'll gladly write up the compare/contrast.
(I'll also note that the silent data loss issue due to indeterminate
escaping in RSS 2.0 was generally brushed aside by its advocates. If
these folks can live with that...)

Final frontier? Anyone done an RDF API in COBOL yet? (Heh, I wouldn't
be surprised to find Redland had a binding for it, it seems to have
for everything else).

Heh, now that path really does lead to a lot of lost time.
