My hope is that a nice application like navibar could foster the 
deployment of content making the semantic web grow. As requirement to 
format I would see:

- free merging of navigation graphs
- multiple navigations for the same set of pages
- easy to understand and use

Imho, things that are not the semantic web way in 
http://navibar.oaklett.org/sitemap.rdf are:
- Lack of type for the classes
- Use of rdf:Seq which makes aggregation harder than with 
parseType="Collection"
- Using plain-literal URIs while in fact the named-resource is meant
- Unnecessary naming of resources with URNs

In my example:
- The resources have a type (SiteMapEntry, but would probably better be 
"NavigationEntry")
- Instead of "identifier" a "page" property points to the page (which is 
a resource)
- parseType="Collection" instead of Seq
- rdfs:label / dc:title: question of taste I guess, could live with 
dc:title ;-)

Like your vocabulary it supports an arbitrary graph-structures including 
circles, and I don't think that it would be any harder to use for an 
application like the current version of navibar, but more likely to be 
of use for more generic aggregators.

Another use-case, where aggregability and graph structure become 
important would be a tool (navibar 2 ?) to visualize an navigate through 
a blog-discussion on multiple servers.
