That's Edd's harvester. My robot ('scutter mk2') only de-references URIs
that you mention, specifically those that have an rdfs:seeAlso property
pointing at them. I dererence PGP/GPG assurances (the .asc files,
typically) only if the signed document references them with a
wot:assurance property. I should document this somewhere.
So we should probably start a Wiki page on FOAFSpiderRules to keep track
of divergence amongst implementations. Counting my (now defunct) Perl
original, we have perl scutter mk1 (undocumented and dead); Libby's Java
stuff (which powers the co-depiction demo), uses Postgres and her
Inkling software; Edd's Redland-based Python tools (with an IRC
interface :) and my new Ruby implementation. This is getting fun, and
also rather hard to keep track of new developments. The Wiki (linked
from http://rdfweb.org/) is a useful way of taking rough and ready
notes. I'm starting to dump some ideas and notes there. Feel free to

Yeah, sounds tricky. Perhaps spawning a new page that emulates the form

Yes, that's pretty nice. Dunno if Leigh's seen that stuff yet.

Wonder how long it'll be before http://images.google.com/ supports
