None of the existing proposals is entirely satisfactory. The most promising framework from the point of view of extensibility and future-proofness would be one constructed on the basis of the OCLC scheme. it is recommended that this be implemented and tested, along with implementation specifications for the other schemes to show how they compare mutually when built on top of this basic framework.
The result of following this recommendation will be a framework within which multiple URN schemes can coexist, each offering their own particular advantages in a given situation, while allowing naming authorities to issue URNs appropriately.
