Sounds like a good idea to me.  My own copy of helper.bml (which I've
turned into a standalone is hacked to do this:

	my $foaf=new XML::FOAF(new URI($vident->url));
	my $identity={
		url  => $vident->url,
		name => eval { $foaf->person->name } || '',
		nick => eval { $foaf->person->nick } || ''
	my $eidentity = js_dumper($identity);

Unfortunately, XML::FOAF is a really heavy module; it depends on
Crypt::OpenPGP, which pulls in about twenty crypto modules, many of
which don't seem to install cleanly via the CPANPLUS shell.  (They
work fine with standard for some reason.)

Actually, this sounds like a much larger idea than just OpenID.  A
module that takes an arbitrary URL, retrieves all the metadata
associated with it, and sets it up in a usable, format-agnostic form
would likely have applications elsewhere.  Suggested name:
WWW::Profile or WWW::AuthorProfile.

Possibly relevant CPAN modules:
    * XML::FOAF
    * WWW::Blog::Metadata
    * Text::vCard and Text::vCard::Addressbook
    * XML::Atom::Person (not well documented)

I seem to have a lot of the same constraints as Mr. Smith (little
knowledge of semantic protocols and limited time), so I don't think I
can tackle this, except in a secondary role.
