2009 Feb 4, 4:30New URN schemes with no central minting authority. duri allows you to name a resource that was identified by the specified URI at the specified date (e.g. refers to the IETF's homepage at the end of
the year 2001). tdb allows you to name a physical object or entity that was described by a resource that was identified by a specified URI at the specified date (e.g. refers to IETF the orginization
as referenced by their homepage at the end of the year 2001). Date format is concise but I'd prefer RFC3339 rather than roping in another date format.
