Dear all,
I don't really intend to fire up a new discussion about GUIDs, but I  
came across some pretty good documents about URIs I thought I share  
with you. They adress pretty much all of our needs for persistent and  
resolvable identifiers in these texts.

(1) http://www.dfki.uni-kl.de/dfkidok/publications/TM/07/01/tm-07-01.pdf
"Cool URIs for the Semantic Web" by Leo Sauermann DFKI GmbH, Richard  
Cyganiak Freie Universität Berlin (D2R author), Max Völkel FZI Karlsruhe
The authors of this document come from the semantic web community and  
discuss what kind of URIs should be used for RDF resources.

(2) http://www.w3.org/2001/tag/doc/URNsAndRegistries-50
This one here is written by the W3C and addresses the questions "When  
should URNs or URIs with novel URI schemes be used to name  
information resources for the Web?" The answers given are "Rarely if  
ever" and "Probably not". Common arguments in favor of such novel  
naming schemas are examined, and their properties compared with those  
of the existing http: URI scheme.

best wishes,
Markus Döring
