<dc:subject> -- ignore, or spaced-out version of the title ("SomeWikiPage" -> 
"Some Wiki Page") 
<dc:title> -- the name of the wiki page, without the Wiki name or other stuff
I think here it means :
<dc:title> eg. Main.HomePage
<dc:subject> Either the spaced out version OR text from (:title:)
I think dc:description means (:description:)
coz if there exist a meta for a bookmark this would sound weird-
<dc:description> -- ignore, or use the first paragraph of the wiki page.

Check here:
    The description of or notes about the bookmark.

Nope, I am not againt it. What I am trying to emphasise is that while 
designing it we keep in mind other rdf models too 
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
i.e other rdf models, dc, annotea, bookmarks.... hmmmm
And the design should be flexible rather modular enough to adapt itself.

I think its not far dedicated meta servers would be ubiquitous.
Shall we christen it DMS or MFS (meta file servers) from where meta files can 
be picked up or shared. :-)
