Good Idea :)

May I suggest that there is a fairly obvious transformation of multi
word phrases to rdf compatable Id's.  Remove punctuation, lower case the
phrase (so will produce more matches) and substitute '_' for space.
  Where a phrase contains a quote, substitute '-' for space inside the
quotation.

For example:

Publishing Place  --> publishing_place

"For Whom the Bell Tolls" by Earnest Hemengway  -->
for-whom-the-bell-tolls_by_earnest_hemengway

Id's of this nature have the advantage of being round trippable between
RDF, N3, Semenglish, and I believe KIF.  Yet they are very human
friendly too!
