This document discusses the Object Identifier (OID) Resolution System, highlighting its concept, history, and the contents of its 2nd Working Draft. An Object Identifier serves as a globally unique identifier for various objects, including ITU-T standards and cryptographic algorithms. The text outlines the system's architecture, resolution processes, and security considerations. Historical milestones, such as the proposal and approval of the OID Resolution System, are documented, alongside contributions from key project editors. The objective is to facilitate efficient information retrieval associated with OIDs.

  1. Progress on OID Resolution System Jun Seob LEE (juns@etri.re.rk) Document number Zhangjiajia, China 8-10 April 2009

  2. Contents Concept History Contents of 2nd Working Draft Issues

  3. 1. Concept of OID Resolution System • Object Identifier (OID) • Definition: A globally unique value associated with an object to unambiguously identify it (ITU-T Recommendation X.680 | ISO/IEC 8824-1) • Variety of objects:ITU-T SG no., countries, Standards, cryptographic algorithm, network, protocol commend, code … Anything • Example • {0 1 17} = ITU-T Study Group 17 • {1 0 15961} = ISO/IEC 15961 • {1 2 410 200004 1 2} = HAS-160 hash algorithm • {0 3 4500} = Korea (Rep. of) HiNET-P (Korea Telecom) • {1 0 15961 126 7} = ReadSingleObjectCommand • OID Resolution System • Definition: A system which provides information associated with any object identified by an Object Identifier

  4. 2. History (1/2) • During the discussion on ITU-T restructuring, new ToR, OID resolution, is added to Q.10 (Q.12) • NP (6N13665) was proposed at July 2008 • NP was approved at October 2008 • JTC 1/SC 6 meeting (Montreux , 3 ~ 7 November 2008) • Project No. (55.01.00) and designate IS no. (29168) were assigned • BRM for NP ballot • 1st Working Draft was submitted to JTC 1/SC 6 at December 2008 • ITU-T SG17 meeting (Geneva, 11 ~ 20 February 2009) • BRM on 1st Working Draft • 2nd Working Draft was submitted to JTC 1/SC 6 at 31 March

  5. 2. History (2/2) • Project editors (both ITU-T SG17 and JTC 1/SC 6) • Mr. Jun Seob LEE (juns@etri.re.kr, Korea) • Ms. Xu Donmei (xudm@cesi.ac.cn, China) • Prof. Byoung-Ho Ahn (bhahn@ok.ac.kr, Korea)

  6. 3. Contents of 2nd Working Draft (1/3) • Title: Object Identifier Resolution System • Contents • OID Resolution System Architecture • Overview • General OID resolution process • Application-specific OID resolution process • The DNS protocol for the general OID resolution process • Query to an OID resolution server • Response from the OID resolution server • Operation of the OID Resolution System • Name space for OID Resolution System • Default setting of zone file for OID Resolution System • Security and Trust Aspects of the OID Resolution System

  7. 3. Contents of 2nd Working Draft (2/3) • Overview of OID Resolution System

  8. 3. Contents of 2nd Working Draft (3/3) • Input to OID resolution server • Canonical form of OID-IRI (ex, /2/27/1) • OID-IRI (ex, /joint-iso-itu-t/tag-based/mcode) • Output from OID resolution server • Access information • Access method and location (ex, HTTP, www.example.com) • Child node information (TBD) • Canonical form of an OID-IRI (ex, /2/27/1)

  9. 4. Issues • Name space for OID Resolution System • New gTLD for OID Resolution System • .oid, oid.itu.int, oid.int … • Default setting of zone file • Security issues • DNSsec
