1. May 7, 1998 Washington DC Bunyip Information Systems Inc Uniform Resource Names (URNs) -- an Update Leslie L. Daigle

2. May 7, 1998 Washington DC Bunyip Information Systems Inc What it means to develop things for the Internet Uniform: accessible to all applications Open discussion/development of standards –interoperable pieces developed by multiple sources –IETF community drives protocol updates, no single vendor Required when no single organization can develop full suite of software for the Globe

3. May 7, 1998 Washington DC Bunyip Information Systems Inc The Proposed URN Framework Looks like: –URN: : For example –URN:ietf:rfc:2141 –NID is ietf –NSS is rfc:2141

4. May 7, 1998 Washington DC Bunyip Information Systems Inc The Proposed URN Framework (Contd) Resolver Discovery Systems Individual resolvers –probably not just for URNs Delegation The client can do whatever it wants

7. May 7, 1998 Washington DC Bunyip Information Systems Inc DOI and URNs A current Wiley DOI: 10.1002/0002-8231(199601)47:1 2.3.TX;2-K which is resolvable through http://doi.wileynpt.com/10.1002/0002-8231(199601)47:1 2.3.TX;2-K could appear as urn:doi:10.1002/0002-8231(199601)47:1 2.3.TX;2-K

May 7, 1998 Washington DC Bunyip Information Systems Inc Distributable delegation The DOI: 10.1002/0002-8231(199601)47:1 2.3.TX;2-K DOI namespace identifies publisher: 10.1002 Publisher identifies subdelegation: –own server: doi.wileynpt.com, using handles protocol –other server: aol.com, using http –corporate subdivision: doi.wileynpt.se, using rwhois Not all protocols support all services

9. May 7, 1998 Washington DC Bunyip Information Systems Inc IETF URN Status By June, 1998, should be able to define URN namespaces A Global NID is deployed -- DNS Prototype code exists for final resolution services Extension to MS-IE, Netscape will be available –thttp, rwhois, rcds –I2L, I2Ls, I2C

10. May 7, 1998 Washington DC Bunyip Information Systems Inc DOI/IETF Steps Forward CNRI is working to ensure Handles compatible as a URN namespace Beyond this rudimentary notion of resolution, what services does the publishing community need? –authentication? e-commerce? searching? With set requirements, IETF tools can be applied or necessary extensions driven
