David,

Even if you don't use RDFa to express what <> is about i.e. it's 
foaf:primarytopic, foaf:topic etc..

In the Exhibit pages <head/> You can accompany:
<link 
href="http://data.semanticweb.org/dumps/conferences/eswc-2008-complete.rdf" 
type="application/rdf+xml" rel="exhibit/data" />
with
<link rel="alternate" 
href="http://data.semanticweb.org/dumps/conferences/eswc-2008-complete.rdf" 
type="application/rdf+xml" />

I think we need to adopt a multi pronged approach to exposing Linked 
Data (the raw data behind the Web Page):

1. Content Negotiation (where feasible)
2. <link rel=.../>  (for RDF sniffers/crawlers)
3. RDFa


Re. point 2, I've just taken a random person "Abhita Chugh 
<http://demo.openlinksw.com/rdfbrowser2/?uri=http%3A%2F%2Fsemanticweb.org%2Fwiki%2FAbhita_Chugh>" 
from <http://data.semanticweb.org> which exposes the RDF based 
Description of "Abhita Chugh" 
<http://demo.openlinksw.com/rdfbrowser2/?uri=http%3A%2F%2Fsemanticweb.org%2Fwiki%2FAbhita_Chugh> 
via our RDF Browser without problems (we use all 3 of the methods above 
to seek "Linked Data" associated with a Web Document). In this case it 
also eliminates the need to translate anything (e.g. routing via Babel)  
since the original data source is actually RDF.

Of course, I could take the exhibit page and slap this in myself, but I 
am hoping you could tweak Exhibit such that it does point 2 and maybe 
point 3 automatically. That would be a major boost re. Exhibit's Linked 
Data credentials :-)
