Subsequent request to inline graphics etc. can be modeled by using RDF 
collections like in example 2.2 of 
<http://www.w3.org/TR/2007/WD-HTTP-in-RDF-20070323/>:

<http:Connection rdf:ID="conn2">
   <http:connectionAuthority>www.example.org:80</http:connectionAuthority>
   <http:request rdf:parseType="Collection">
     <http:Request rdf:about="#req0"/>
     <http:Request rdf:about="#req1"/>
   </http:request>
</http:Connection>

I think we already thought about adding time properties. The HTTP spec 
talks about time in the section on caching. You could add e.g. 
http://purl.org/dc/terms/created or refinements like 
http://purl.org/dc/terms/dateSubmitted to the Request resources. Usually 
the server already sends a Date header. But you could additionally add 
your local date/time to the Response resource.
