Thanks Eric... Instead of an rd:Foo, I made it an is:Document
(xmlns:is="") and that seemed to work.
It still doesn't look right in the sidebar when I view, but I assume that that's caching
issues--a copy of pbtest.html that points at a revised copy of pbtest.rdf
does show what I expected in the sidebar.

I think that dealing with untyped nodes in proper RDF should be a higher
priority than dealing with non-RDF, because Piggy-Bank already goes so far
in breaking the chicken/egg cycle of
not-enough-RDF-data-out-there/no-good-apps-to-take-advantage-of-RDF-data. If can find triples in an RDF file, then
Piggy-Bank should be able to do something with them.

quick hack... s/rdf:Description/rd:Foo/

In essence you're saying '' is a
rdf:type rd:Foo.

That being said, it strikes me when Fresnel is integrated into Longwell
(which in turn would then be in Piggy-Bank) there should be some simple
vanilla abilities to display untyped nodes.

Another simple, similar example is available at

<link rel="meta" type="application/rdf+xml" title="Contact"
href="contact" />

digging into we see

<?xml version="1.0"?>

<rdf:RDF xmlns:rdf=""
          xmlns = "">

   <Person rdf:about = "">
     <rdf:value>Eric Miller,</rdf:value>
     <mailbox rdf:resource = "" />
     <homePage rdf:resource = "" />
     <fullName>Eric Miller</fullName>
     <personalTitle>Semantic Web Activity Lead</personalTitle>
     <company>W3C World Wide Web Consortium</company>


let me know if this works for you... I must admit, I really like the idea
of using Piggy-Bank to store (among other things) contact information :)
