The URI (Uniform Resource identifier) Working Group is currently stalled on the issue of how to implement URNs. There is no shortage of proposals, but no single proposal has been perfected, and all contain shortcomings which have prevented them gaining widespread support from the members of the working group.
The aim of this document is to criticise the existing proposals in a constructive manner, so as to draw out their positive qualities, and then to develop a modular scheme for combining these best components into new URN schemes.
Some specific architectural considerations are derived and discussed in the following section.
